'''Probing the Central Parsec of Active Galactic Nuclei with Water Masers''' <br>
Determining the geometry and dynamics of the inner-most parsec of active galactic nuclei (AGN) is critical for understanding accretion and the relationship between the AGN and host galaxy. Water maser emission at 22 GHz provides a unique tracer, resolvable in position and velocity, of warm, dense molecular gas ~0.1-1.0 pc from the central engine. Furthermore, water masers exist in the narrow temperature range of ~400-1000K and can be used to probe the temperature and temperature gradient inside the AGN disk. I will discuss i) a test of disk heating in accretion models, using maser spectra and VLBI maps, ii) a study of the flow of material in NGC 4945, combining maser VLBI maps and multi-wavelength data, and iii) a search for new maser systems in the Southern Hemisphere, the Tidbinbilla AGN Maser Survey (TAMS).

'''Particle acceleration during magnetic reconnection in ultrarelativistic electron-positron plasmas''' <br>
In pulsar winds and jets from AGNs, plasma is considered to be composed of ultrarelativistic electrons and positrons with their Lorentz factors 10^3 to 10^6. How these high energy particles are produced is an open question, and magnetic reconnection is one of mechanisms to accelerate particles. We study magnetic reconnection in ultrarelativistic electron-positron plasmas by means of 2-D simulations that include kinetics of particle motion, and investigate particle acceleration mechanisms and energy spectra of accelerated particles.

'''Planck 2015 Constraints on the Cosmic Neutrino(-like) Background''' <br>
The Planck 2015 results include the tightest measurements to-date of cosmic microwave background (CMB) temperature and polarization anisotropies up to few-arcminute angular scales. I will give a broad overview of the cosmology results from these data, with particular focus on what we have learned about the cosmic neutrino background (CNB). The new data allow more precise answers to questions such as 1) how much energy, parameterized by N_eff, is contained in the CNB? 2) what is the sum of the masses of the particles making up the CNB? and 3) are these particles really neutrinos, i.e. do they free-stream like neutrinos? One possibility I will explore is if some component of the CNB actually comes from axions or axion-like particles. Recent improvements in CMB and BBN data are shedding new light on this scenario. I will also discuss the status of agreement between Planck results and other cosmological probes such as BAO, H0, and low redshift structure measurements, and how the CNB may play a role in resolving tensions between some of them.

'''Cosmology from the One-Point Function''' <br>
Cosmological measurements have traditionally focused on the two-point correlation function or power spectrum. However, due to the non-gaussianity of the late-time density field, a vast amount of information potentially lies in the one-point probability distribution function (PDF) of various cosmological observables, such as the weak lensing (WL) convergence or thermal Sunyaev-Zel’dovich (tSZ) effect. We present analytic methods that allow for straightforward and efficient computations of these signals. Using data from the Atacama Cosmology Telescope (ACT), we explicitly demonstrate the power of the tSZ PDF, constraining the amplitude of density fluctuations with an error bar nearly twice as small as that obtained from ACT's earlier analysis of the tSZ skewness alone (with the same data). We extend these methods to the WL convergence field, for both CMB lensing and galaxy lensing, and verify their accuracy by comparing to ray-traced N-body simulations. Combining the WL PDF and power spectrum will increase the cosmological constraining power of upcoming surveys by at least a factor of two.

'''CARMA Large Area Star Formation Survey (CLASSy)''' <br>
I will present recent results from the CARMA Large Area Star Formation Survey (CLASSy) with a focus on the structures and kinematics of dense gas in Serpens Main. The survey mapped 150 square arcminutes of Serpens Main with an angular resolution of 7 arcsecs using N2H+(1-0), HCO+(1-0), and HCN(1-0) as dense has tracers. The gas emission is concentrated in two subclusters (the NW and SE subclusters). The SE subcluster has more prominent filamentary structures and more complicated kinematics compared to the NW subcluster. I will talk about the properties of the filaments, and their implications to the formation of the SE subcluster. Also, I will compare the properties of the filaments with the distribution of YSOs. The comparison suggests that the YSOs are formed on gravitationally unstable filaments. Finally, I will show velocity gradients perpendicular to the filaments at 0.03 pc scale across CLASSy regions. Such velocity gradients can be a natural consequence of converging flows.

'''Investigating the Milky Way’s Nuclear Outflow Kinematics''' <br>
Recent observations with gamma ray emission to microwaves and polarized radio waves have detected giant lobes of plasma (Fermi Bubbles) extending above and below the Galactic plane of the Milky Way. These are possible signs of a Nuclear wind powered by either the central black hole or high-surface-density star formation, but our understanding is hampered by a lack of kinematic information. I will report the first results of a HST/COS survey to constrain the velocity of the outflowing gas within these regions, using ultraviolet absorption-line spectra.We perform a comprehensive spectroscopic program to survey the nuclear outflow in both the northern and southern Galactic hemispheres.We combine high-resolution STIS E140M observations of distant halo stars at low latitude with medium-resolution COS observations of AGNs at higher latitude. These sightline pass through a clear biconical structure seen in hard X-ray and gamma-ray emission of the Fermi Bubble. I will report detections of high velocity metal absorption lines, which cannot be explained by co-rotating gas in the Galactic disk or halo. Their velocities are suggestive of an origin on the front and back side of an expanding biconical outflow emanating from the Galactic center. We develop simple kinematic biconical outflow models that can explain the observed profiles with an outflow velocity of ~900/1000 km/s and a full opening angle of ≈110° (matching the X-ray bicone). This indicates Galactic center activity over the last ≈2.5-5.0 Myr, in line with age estimates of the Fermi Bubbles. The observations illustrate the use of UV spectroscopy to probe the properties of swept-up gas venting into the Fermi Bubbles.

'''Perturbative interaction approach to cosmological structure formation'''

The statistical properties of cold dark matter (CDM) in the non-linear regime make for a technically challenging problem, and their study has been the bread-and-butter of several generations of cosmologists. Standard analytical methods improve upon linear perturbation theory on quasi-linear scales, but usually fail dramatically at non-linear scales. A new and promising method was recently introduced by researchers in the field, relying on an expansion in the gravitational interaction, and using mathematical tools inspired by those of quantum field theory. This method seemed to produce results in good agreement with numerical simulations, deep inside the non-linear regime. In this talk, after reviewing standard perturbation schemes, I will lay out a simpler formalism for the perturbative interaction approach, using implicit forms for particle trajectories. I will show that this approach fails at recovering the linear growth factor on large scales, and that the apparent agreement on non-linear scales results from unjustified approximations. The problem of finding an analytical description of non-linear scales therefore remains open.

'''Future SNIa surveys and Blackbody Spectra'''

Hyper Suprime-Cam (HSC) is a new wide-field camera on Subaru Telescope in Hawaii. HSC has a 1.5-degree field-of-view (FOV) in diameter with 104 CCD chips and 5 broad-band filters (g,r,i,z,y). Started from March 2014, a five-year survey program has been running, and I will introduce the survey plan and current status with emphasis on Type Ia supernova (SNIa) survey. Also, I will introduce a potential mid-size IR satellite mission, WISH (http://wishmission.org/en/index.html). In SNIa cosmology, the reduction of the systematic error is an urgent task, and I will propose how to reduce the calibration error by using white dwarfs with nearly a perfect blackbody spectrum.

'''Massive Star Geriatrics''' <br>

The evolution of the most massive stars such as Eta Carinae is controlled by the effects of mass-loss. Understanding these stars is challenging because no true analogs of Eta Car have been clearly identified in the Milky Way or other galaxies. Copious mass-loss leads to circumstellar dust formation, obscuring the star in the optical. But as the light is re-emitted by the dust, these objects become very luminous in the mid-IR. We have carried out a systematic search for Eta Car analogs in 7 galaxies, utilizing data from Spitzer, Herschel, HST and other sources. Our search detected no true analogs of Eta Car, however, we do identify a significant population of 18 lower luminosity (log(L/L_sun)=~5.5-6.0) dusty stars. This is consistent with all 25 < M < 60 M_sun stars undergoing an obscured phase at most lasting a few thousand years once or twice. The mass of the obscuring material is of order ~M_sun, and we simply do not find enough heavily obscured stars for these phases to represent more than a modest fraction (~10% not ~50%) of the total mass lost by these stars. While this search has been feasible using archival Spitzer data, JWST will be a far more powerful probe of these stars. The HST-like resolution of JWST will greatly reduce the problem of confusion and expand the possible survey volume.

'''Clues to Galaxy Formation from the Milky Way's Cosmological Context''' <br>

Very different data sets guide galaxy formation theory across cosmic history: from the global properties of >10^7 galaxies at high redshift (z>0.5) to the kinematics and chemistry of >10^6 stars here in the Milky Way. Traditional observational and computational limitations have dictated independent study of these two regimes. I will discuss how this picture is changing rapidly and how viewing the MW as important boundary condition on galaxy evolution puts unprecedented demands on galaxy formation theory. In particular, I will discuss a novel disk formation mechanism and its signature in current observations of the Milky Way and the resolved kinematics of high redshift galaxies. Modern, high-resolution, cosmological galaxy formation simulations reveal that disks can grow ``upside-down" in the sense that progressively younger stellar populations are born with increasingly smaller vertical velocity dispersion, tracing the kinematics of the collapsing gas disk from which they form. We find that the upside-down model matches the most stringent observational constraints here in the MW, including the steep stellar age-velocity relationship measured in the solar neighborhood. I will argue that traditional interpretations of the MW stellar AVR contradicts evidence from IFU observations of high-redshift disk galaxies and must be revised. Our findings suggest that the "upside-down" model is currently the only self-consistent formation mechanism able to match kinematic constraints from z~2 to z~0. I will conclude with preliminary, yet tantalizing, evidence connecting the star formation history of simulated galaxies with their detailed morphology.

'''Evolving Galaxies in a Dark Universe''' <br>

A fundamental goal in observational cosmology is to understand the link between the luminous properties of galaxies and the dark matter halos in which they reside. Because this link is fundamental to processes that determine the growth, evolution, and global properties of galaxies, key insight can be gained by mapping how the distributions of dark and luminous matter vary across different scales and over cosmic time. In this talk I will discuss new methods to probe the galaxy-halo connection from galaxy scales (tens of kpc to 100 kpc) out to the scale of dark matter halos, themselves (hundreds of kpc to a Mpc). On the smallest scales, I will show that novel weak lensing techniques applied to upcoming surveys such as WFIRST and Euclid can map the inner density profiles of galaxies and provide strong constraints on the inner slope of dark matter as well as the stellar IMF. In the second half of the talk I will shift to the largest scales where a combination of probes provides insight about how galaxies grow (or do not grow) in relation to their global reservoirs of fuel. In particular, I will present a new, comprehensive framework that describes how the most massive galaxies populate dark matter halos and how their colors may be determined by their halo assembly history. Even before more powerful constraints from future surveys, I will show how such models combined with state-of the art measurements of weak gravitational lensing and galaxy clustering from the CS82 and BOSS surveys are already yielding surprising discoveries.

'''Scaling Sunyaev-Zel'dovich Observables to Dark Matter Halos for Cluster Cosmology ''' <br>
The Sunyaev-Zel’dovich effect (SZE) is a powerful tool to study galaxy clusters out to large radii and to detect clusters at high redshifts. To first order, clusters are self-similar and one can link the SZE signal to a cluster’s physical properties by assuming a spherical distribution of matter in hydrostatic equilibrium. The SZE signal, however, will be affected by any astrophysical process that contributes non-thermal pressure support or if the cluster has non-spherical morphology. We have measured the SZE signal of 45 massive clusters using Bolocam at 140 GHz. After measuring the scaling relations of the SZE signal with total cluster mass, we find our clusters to be approximately 5-sigma shallower than the self-similar HSE prediction--a result that is in tension with most other SZE scaling relations studies. To confirm our measurements, we have implemented a series of tests to see whether, among others, sample selection, redshift, degree of disturbance, or alternative mass proxies might affect our measurements. We believe our results to be robust to the extent to which we are able to constrain the cluster properties with current observations. If confirmed, this would have a major impact on our understanding of galaxy clusters and cluster cosmology.

'''Constraints on the Efficiency of Radial Migration in Spiral Galaxies''' <br>
A transient spiral pattern can permanently rearrange the orbital angular momentum distribution of a stellar disk without inducing kinematic heating. This redistribution happens around the radius of corotation, where the circular orbital frequency equals the spiral pattern speed, and leads to what is now called “radial migration”. Should radial migration be an efficient process it could cause a large fraction of disk stars to experience significant changes in their individual orbital angular momenta over the lifetime of the disk. Such scenarios have strong implications for the chemical, structural and kinematic evolution of disk galaxies. I present some results from an investigation into the physical dependencies of the efficiency of radial migration on stellar kinematics and spiral structure.

'''Primordial non-Gaussianity in the CMB and Large-Scale Structure''' <br>
I'll give a pedagogical review of inflation and explain how its physics can be constrained by searching for "primordial non-Gaussianity", i.e., differences between the statistics of the initial curvature field in our universe and the statistics of an ideal Gaussian field. Then I'll talk about observational CMB constraints, including some new results from Planck. Finally I'll discuss future prospects for improving Planck constraints with large-scale surveys such as Euclid and LSST.

'''Probing the Connection Between the Circumgalactic Medium and the Interstellar Medium of Galaxies''' <br>

We present the first statistical study probing the connection between the circumgalactic medium (CGM) and the atomic hydrogen content within galaxies. The survey utilizes Hubble Space Telescope ultraviolet spectroscopy to probe the hidden baryonic content in the CGM for 47 galaxies from the GALEX Arecibo SDSS Survey (GASS).

We find strong correlations between the amount of H I gas in the ISM of the galaxies and the neutral gas content in the CGM. These are stronger than the analogous correlations between the star-formation rates and the CGM content. Additionally, the velocity spread of the circumgalactic gas is consistent with that seen in the atomic gas in the interstellar medium. These results imply a physical connection between the H I disk and the CGM on scales an order-of-magnitude larger. This is consistent with the picture in which the H I disk is nourished by accretion of gas from the CGM.

'''CLASS: The Cosmology Large Angular Scale Surveyor ''' <br>
The detection and characterization of the primordial B-modes in the polarization of the cosmic microwave background (CMB) is one of the next major steps in developing our understanding of the early universe. Primordial B-modes, a divergence-free polarization pattern in the CMB, are solely sourced by gravitational waves created during the epoch of inflation. Detecting the primordial B-modes would represent a “smoking gun” for inflation and provide evidence of a period of exponential expansion in the early universe. The detection of the primordial B-modes requires a precise measurement of the CMB polarization on large angular scales with multiple frequencies for galactic foreground removal. The Cosmology Large Scale Angular Surveyor (CLASS) is a four frequency telescope array with a rapid front-end polarization modulator sited in the Chilean Atacama desert, making it uniquely suited for detecting the primordial B-mode signal.

'''From Accretion Flow to Particle Acceleration: New Relativistic Magnetohydrodynamic Jet Solutions''' <br>

Observations of jets show us that the electrons throughout the jet have a power-law energy distribution, even though the electron cooling time due to radiation is much shorter than the lifetime of the jet. This result implies that the electrons are continuously accelerated in the jet, and we associate the onset of this process with a shock at the outermost magnetohydrodynamic (MHD) singular point in the outflow.

I will give a short overview of MHD jet physics, and show how we developed a semi-analytical model that describes the jet from very close to the black hole to this first shock, allowing us to better model the expected emission from a black hole system.

'''On whether supermassive black holes can be explained by primordial black holes''' <br>
Supermassive black holes and intermediate mass black holes are believed to exist in the Universe. There is no established astrophysical explanation for their origin and considerations have been made in the literature that those massive black holes (MBHs) may be primordial black holes (PBHs), black holes which are formed in the early universe (well before the matter-radiation equality) due to the direct collapse of primordial overdensities. I will discuss the possibility of excluding the PBH scenario as the origin of the MBHs. I first revisit the constraints on PBHs obtained from the CMB distortion that the seed density perturbation causes. I also discuss a new method which can potentially exclude small PBHs as well. We first observe that large density perturbations required to create PBHs also result in the copious production of ultracompact minihalos (UCMHs), compact dark matter halos formed at around the recombination. From this observation, we show that weakly interacting massive particles (WIMPs) as dark matter annihilate efficiently inside UCMHs to yield cosmic rays far exceeding the observed flux. Our bound gives severe restriction on the compatibility between the particle physics models for WIMPs and the PBH scenario as the explanation of MBHs.

'''Fe K-alpha Emission Lines from Simulations of Black Hole Accretion''' <br>
The Fe K-alpha fluorescent emission line is a ubiquitous spectral feature in observations of both stellar-mass black holes and active galactic nuclei. It originates from X-ray irradiation of the accretion disk, which extends deep into the gravitational well---thus the Fe K-alpha line provides an excellent diagnostic of the physical conditions and spacetime geometry in the vicinity of the black hole. I will describe how, starting from genuine physical principles and introducing as few assumptions as possible, we produce theoretical predictions for the Fe K-alpha line shape and intensity. In addition, I will give a brief comparison to and discussion of some current Fe K-alpha observations. Finally, I will discuss some frontier applications of this work, e.g., the use of X-ray reflection spectroscopy in the measurement of black hole spin.

'''Pushing the radial-velocity precision to unveil Earth-mass exoplanets''' <br>
At the meter per second precision reached by the best nowadays radial-velocity (RV) spectrographs, very subtle signatures of astrophysical noises start to be revealed. From a nearly continuous timescale ranging from several minutes to several years, stellar oscillations, granulation phenomena, short-term and long-term activity induce a RV signal that mask the RV signature induced by small-mass planets orbiting far from their host star.
Some of these astrophysical noises are now well understood and strategies to average them out have been found, however still an important work needs to be done for other sources of noise.
During my talk, I will give an overview of the work that have been carried on these last years and will try to focus on the main nowadays limitations.

'''Mega-SH0ES: Searching for Cepheid Variables in Type Ia Supernova Host Galaxies''' <br>
The Mega-SH0ES project aims to measure the Hubble constant to percent-level uncertainty. As part of this ongoing effort, we determine accurate and precise Cepheid distances to host galaxies of type Ia supernovae within 50 Mpc. I will present preliminary results from our latest HST/WFC3 observations, in which time-series data is obtained using a long pass filter (F350LP) to detect variability while conserving orbits and infrared images (F160W) are used to construct a precise P-L relation with low systematic uncertainty. We combine the new targets with the ones previously analyzed in Riess et al. (2011) and will calibrate the Extragalactic Distance Scale with a record 17 SNeIa host galaxies.

'''Relativistic clustering and separate universes''' <br>
The separate universe conjecture states that in General Relativity a long-wavelength density perturbation affects physics locally such that short-scale gravitational clustering takes place in a separate universe with different background density and curvature. We construct Conformal Fermi Coordinates to verify this conjecture for small cosmological scalar perturbations on arbitrary scales. In this case, the isotropic part of the perturbation is entirely absorbed into a modified local expansion history and spatial geometry. The anisotropic part, on the other hand, is exactly captured by a tidal field in the Newtonian form. The separate universe picture is restricted to scales larger than the sound horizons of relevant cosmic fluids. Using this formalism, an expression can be derived for the locally measured matter bispectrum induced by a long-wavelength mode of arbitrary wavelength, a new result which in standard perturbation theory is equivalent to a relativistic second-order calculation. It can be shown that nonlinear gravitational dynamics does not generate nonlinear clustering that scales like local-type primordial non-Gaussianity f_NL. Rather, contamination to f_NL type non-Gaussianity only arises from relativistic projection effects on photon propagation, which depend on the specific large-scale structure tracer and observable considered, and are in principle distinguishable from nonlinear gravitational clustering.

'''APOGEE I/O: Efforts to Effectively Harness the Large Scale Data Set of the APOGEE 1+2 Survey''' <br>
The first phase of the Apache Point Observatory Galactic Evolution Experiment (APOGEE-1), a cornerstone project of the Sloan Digital Sky Survey III (SDSS-III), performed a large-scale, spectroscopic survey of the Milky Way conducted from the Northern Hemisphere, aimed at tracing the chemodynamical evolution of the Milky Way. Now, the SDSS-IV APOGEE-2 Survey is underway, with observations being carried out at both Northern and Southern Hemisphere locations. APOGEE acquires high-resolution, high signal-to-noise spectra in the H-band (1.51-1.69 microns) and produces stellar atmospheric parameters, individual element abundance ratios for 15 species, and radial velocity measurements for its stars. By 2020, data will have been collected for several hundred thousand stars from all components of the Galaxy (all disk quadrants, the inner and outer halo, the full expanse of the bulge, and local satellites). Accordingly, the combined APOGEE 1+2 data set is tailor-made for the comprehensive and systematic examination of Galactic formation and evolution. I will give an updated overview of the APOGEE 1+2 Survey, briefly discuss endeavors to improve the data product determination (such as enhancing the atomic physics inputs), and describe initial data mining efforts and the use of APOGEE data products to assemble composite chemical and kinematic profiles for target stellar populations.

'''Optimal estimator for resonant bispectra in the Cosmic Microwave Background''' <br>
With a cosmic variance limited measurement of the CMB power spectrum we have almost exhausted the information available in the almost Gaussian CMB. Within the next years we hope to further explore the polarization and measure higher order correlation functions in the CMB that improve our understanding of the early Universe. In this talk I will focus on a particular class of CMB bispectra known as resonant bispectra. These spectra have rapidly varying features on top of the late-time BOA features. Only recently, and only for a limited number of frequencies, have these bispectra been constrained using the Planck data. I will discuss a newly proposed estimator of such bispectra and show that we should be able to probe any frequency that one expect from an EFT argument (and beyond), because the estimator relies on the fact that most of the theoretical shapes are at most 1 dimensional (while the full bispectrum is 3 dimensional).

'''Theoretical Predictions of Large Scale Clustering in the Lyman-alpha Forest''' <br>
With the recent progress of Lyman-alpha forest power spectrum measurements, understanding of the bias between the measured flux and the underlying matter power spectrum is becoming crucial to the percent level cosmological interpretation of these measurements. Whereas previous theoretical studies of this bias have used N-body and hydro-PM simulations, we have run hydrodynamic simulations to study the response of the Lyman-alpha forest clustering to large wavelength modes of the underlying matter large-scale structure. Our results demonstrate that this can be simulated by evolving smaller, curved universe cosmologies, representing the same universe with different overdense patches. We use these to study the assumptions of the analytical bias formula derived by Seljak (2012), and compare these results with previous numerical methods of determining bias. With several forthcoming large data sets, such theoretical predictions are important to fully understand the clustering of the Lyman-alpha forest and its cosmological implications.

'''The First z>2 Large-Scale Structure Map with Lyman-Alpha Forest Tomography from LBGs''' <br>
The hydrogen Lyman-alpha forest is a long-established probe of large-scale structure at z>2, but is typically limited to 1D investigations along individual quasar sightlines. However, by instead targeting LBGs as background sources, the transverse separation between sources is ~Mpc and it becomes possible to do a 3D 'tomographic' reconstruction of the intergalactic medium. I will describe pilot observations using this technique, which has produced the first map of 3D large-scale structure at z~2.3 within the COSMOS field. Comparisons with coeval galaxies and simulations indicate that our map is truly tracing large-scale structure. This motivates the CLAMATO survey, which will map out a volume of (100 Mpc/h)^3 at z~2.3 and allow us to search for galaxy protoclusters, study the effect of environment on galaxy evolution, and constrain cosmological parameters.

'''Close Pairs: Observational Probes for how Halo Accretion Impacts Galaxy Star Formation''' <br>

We present a simple observational method for selecting galaxies whose host dark matter haloes have had significantly higher-than-average accretion rates. The method relies on using close pairs of galaxies to preferentially identify major dark matter halo mergers. Applying the method to central L∗ galaxies in the Sloan Digital Sky Survey (SDSS) DR10, we find no evidence for enhanced average or median star formation accompanying as much as an 0.3 dex increase in average halo accretion rates. However, population subsamples do show enhancements. Most interestingly, star-forming L∗ galaxies show a double peak in star formation enhancements as a function of the distance to the close pair. The larger (factor of 2) enhancement occurs for close pairs within 30 kpc, and the smaller (factor of 40%) enhancement occurs for pairs separated by 100-200 kpc (i.e., just within the virial radius of the larger galaxy’s halo). We discuss implications for conditional abundance matching models; while galaxy quenchedness cannot depend only on halo mass and recent accretion, reproducing the full behaviour of star-forming galaxies requires more advanced models than currently exist.

'''A 400 solar mass black hole revealed while mimicking a stellar-mass black hole ''' <br>
The brightest X-ray source in M82 has been thought to be an intermediate-mass black hole (100-10,000 solar masses) because of its extremely high X-ray luminosity and variability characteristics, although some models suggest that its mass may be only of the order of 20 solar masses. The previous mass estimates were based on scaling relations which used low-frequency characteristic timescales which have large intrinsic uncertainties. In stellar-mass black holes we know that the high frequency quasi-periodic oscillations that occur in a 3:2 ratio (100-450 Hz) are stable and scale inversely with black hole mass with a reasonably small dispersion. The discovery of such stable oscillations thus potentially offers an alternative and less ambiguous mass determination for intermediate-mass black
holes, but has hitherto not been realized. I will discuss the discovery of stable, twin-peak (3:2 frequency ratio) X-ray quasi-periodic oscillations from M82 X-1 at the frequencies of 3.32 Hz and 5.07 Hz and how this helps overcome the systematic uncertainties present in previous studies. Assuming we can extend the stellar-mass relationship, we estimate its black hole mass to be 428+/-105 solar masses. (See also [http://www.nature.com/nature/journal/v513/n7516/full/nature13710.html this paper] for more information.)

'''AEGIS+PRIMUS: The Clustering of X-ray, mid-IR, and radio-selected AGN''' <br>

We present a clustering study of X-ray, mid-IR, and radio-selected active galactic nuclei (AGN) at 0.2 < z < 1.2 using multi-wavelength imaging and spectroscopic redshifts from the PRIMUS and DEEP2 redshift surveys, covering 7 separate fields spanning ~10 square degrees. Using the cross-correlation of AGN with dense galaxy samples, we measure the clustering scale length and slope, as well as the bias, of AGN selected at different wavelengths. We compare the clustering of each AGN sample with galaxy samples with the same stellar mass, star formation rate, and redshift distributions as the AGN host galaxies and find no significant difference in the clustering of AGN with matched galaxy samples. The observed differences in the clustering of AGN selected at different wavelengths can therefore be explained by the clustering differences of their host populations. We further find no significant difference between the clustering of obscured and unobscured AGN, using IRAC or WISE colors or X-ray hardness ratio.

'''Rotational Spectroscopy of Interstellar PAHs''' <br>
Polycyclic aromatic hydrocarbons (PAHs) are believed to be ubiquitous in the interstellar medium. Yet, to date no specific PAH molecule has been identified. In this talk I describe a new observational avenue to detect individual PAHs, using their rotational line emission at radio frequencies. Previous PAH searches based on rotational spectroscopy have only targeted the bowl-shaped corannulene molecule, with the underlying assumption that other polar PAHs are triaxial and have a complex and diluted spectrum unusable for identification purposes. I will show that the asymmetry of planar, nitrogen-substituted symmetric PAHs is small enough that their rotational spectrum, when observed with a resolution of about a MHz, has the appearance of a "comb" of evenly spaced stacks of lines. The simple pattern of these "comb" spectra allows for the use of matched-filtering techniques, which can result in a significantly enhanced signal-to-noise ratio. Detection forecasts are discussed for regions harbouring "anomalous microwave emission", believed to originate from the collective PAH rotational emission. A systematic search for PAH lines in various environments is advocated. If detected, PAH "combs" would allow to the conclusive and unambiguous identification of specific, free-floating interstellar PAHs.

'''Imaging in the FUSE Band: The Sub-Lyman alpha Explorer''' <br>
I will present our concept for a Small Explorer that will provide 2 arc second imaging in the 1020 – 1200 angstrom bandpass. Our primary science goals are to directly measure the ionizing escape fraction at low redshift, to quantify the contribution of O stars to galactic energy cycles, and probe the physics of proto-planetary disks. There will be a guest investigator program after the prime science surveys have been completed. The design utilizes dispersive re-construction to create a tunable bandpass below Lyman alpha, so that sub-bandpasses can be created in the 1020 – 1200 angstrom region. I will review the science cases and the optical design. If selected, launch would be in 2020.

'''Compact Galaxies and Super Massive Black Holes''' <br>
Super-massive black holes reside at the center of galaxies. And the masses of these black holes correlate to various properties of their host galaxies. These correlations are the foundation for theories of the (co-)evolution of super-massive black holes and their host galaxies. <br>

However, very few galaxies are nearby enough for direct black hole mass measurements. To find suitable galaxies, we surveyed a thousand galaxies with the Hobby-Eberly Telescope. The first results of this survey was the discovery of a dozen extremely compact, high-dispersion, galaxies, which are candidates to host extraordinary massive black holes. The prototype is NGC1277, which is a small, Re=1kpc, compact, lenticular galaxy which hosts a 10 billion solar mass black hole. Which is a significant fraction of this galaxies mass. These highly compact galaxies appear to be the passively evolved descendants of the red nuggets, sub-mm galaxies, and quasars found at high redshifts.

'''Can We Really Trust All That We Know on Short GRBs?''' <br>
The study of short GRBs took a great leap since the arrival of Swift, 10 years
ago. However still, a large part of our newly gained knowledge of these events,
rely on a relatively small sample of bursts with good enough localization. As
there is an overlap with the much more abundant population of long GRBs
(with different origin than the short GRBs), there is a risk that contamination by falsely identified long GRBs may alter some of these conclusions.
In this talk I will show evidence that such a contamination does exist in the
current sample of the short GRBs that are studied (chosen with the criterion
of T_90<2 sec). I will then quantify this contamination, based on our knowledge
of the nature of long GRBs, and demonstrate how it affects some of our conclusions
regarding short GRBs.

'''Joint reconstruction of galaxy clusters from all observables''' <br>
Galaxy clusters provide five types of observables related to their matter distribution: strong and weak gravitational lensing, X-ray emission, the thermal Sunyaev-Zel'dovich effect, and galaxy kinematics. In the talk, I will show how all these observables can be combined in a non-parametric way into a joint reconstruction of the projected gravitational cluster potential. First examples of cluster potentials reconstructed from X-ray emission, the thermal SZ effect and galaxy kinematics will be given.

'''The Science of Deduction: Interpreting Observations of the Epoch of Reionization''' <br>
Up until very recently, the Epoch of Reionization has been largely observationally unexplored . However, with advancements of modern telescopes, we are now able to observe this period of the Universe in multiple ways. While observations are still very challenging due to a host of foreground contaminants, combining observations at multiple wavelengths can lead to a greater understanding of the populations of stars and galaxies at these redshifts. I will describe two of these observables: the Cosmic Infrared Background, which is partially the integrated light from all stars and galaxies at high redshifts, and the 21cm Background, which results from emission from neutral gas. These observables, when paired with theory and simulations, can tell us about some of the first stars and galaxies that formed within our Universe.

Supermassive black holes (BHs) live at the heart of essentially all massive galaxies with bulges, power AGN, and are thought to be important agents in the evolution of their hosts. However, the origin of the first supermassive BH "seeds" is far from understood. While direct observations of these distant BHs in the infant Universe are unobtainable with current capabilities, massive BHs in present-day dwarf galaxies offer another avenue to observationally constrain the masses, host galaxies and formation path of supermassive BH seeds. Using optical spectroscopy from the SDSS, we have increased the number of known dwarf galaxies hosting massive BHs by more than an order of magnitude. These dwarf galaxies have stellar masses comparable to the Magellanic Clouds and contain some of the least-massive supermassive BHs known. I will present results from this study, and well as on-going efforts using radio and X-ray observations to reveal massive BHs in star-forming dwarfs that can be missed by optical diagnostics.

'''Stellar Tidal Disruption: the Role of General Relativity''' <br>
In tidal disruption events (TDEs), stars passing too close to supermassive black holes (SMBHs) are violently torn apart. I will discuss several recent findings about the light curves of these events, including the role of orbital pericenter, ways in which the spin of the SMBH can be imprinted into TDE light curves, and possible emission of high frequency gravitational waves. I will also discuss an ongoing project focused on how highly eccentric debris streams from a TDE can circularize into a luminous accretion disk. It appears likely that the circularization process is mediated by general relativistic effects: circularization is aided by apsidal precession and hindered by nodal precession due to Lense-Thirring torques.

'''Hydrodynamic Circularization of Stellar Tidal Disruption Debris''' <br>
Black holes in galaxies are powerful central engines capable of
generating accretion flares and jets. A star passing too close to one
will tidally disrupt with some of its debris ejected from the system
while the rest funnels towards the black hole forming an accretion
disk. The emission properties are likely dependent on the mass and
spin of the black hole. The process by which debris forms a disk and
generates flares and/or jets is not well-understood. We investigate
this process by simulating the circularization of stellar tidal
disruption debris. We combine a high-resolution relativistic
hydrodynamic simulation of the star itself as it is torn apart with a
well-resolved relativistic hydrodynamics simulation of the subsequent
motion of the stellar debris as it orbits the black hole. With these
tools, we track the evolution of such a system long enough for 80% of
the stellar mass bound to the black hole to join the accretion
flow. We find significant departures from classical expectations for
the lightcurve associated with tidal disruptions.

'''Herschel Far-infrared Photometry of the Swift Burst Alert Telescope Active Galactic Nuclei Sample of the Local Universe. I. PACS Observations''' <br>
Far-Infrared (FIR) photometry from the Photodetector Array Camera and Spectrometer on the Herschel Space Observatory is presented for 313 nearby, hard X-ray selected galaxies from the 58 month Swift Burst Alert Telescope (BAT) Active Galactic Nuclei catalog. The present data do not distinguish between the FIR luminosity distributions at 70 and 160 um for Seyfert 1 and Seyfert 2 galaxies. This result suggests that if the FIR emission is from the nuclear obscuring material surrounding the accretion disk, then it emits isotropically, independent of orientation. Alternatively, a significant fraction of the 70 and 160 um luminosity could be from star formation, independent of active galactic nucleus (AGN) type. Using a non-parametric test for partial correlation with censored data, we find a statistically significant correlation between the AGN intrinsic power (in the 14-195 keV band) and the FIR emission at 70 and 160 um for Seyfert 1 galaxies. We find no correlation between the 14-195 keV and FIR luminosities in Seyfert 2 galaxies. The observed correlations suggest two possible scenarios: (1) if we assume that the FIR luminosity is a good tracer of star formation, then there is a connection between star formation and the AGN at sub-kiloparsec scales, or (2) dust heated by the AGN has a statistically significant contribution to the FIR emission. Using a Spearman rank-order analysis, the 14-195 keV luminosities for the Seyfert 1 and 2 galaxies are weakly statistically correlated with the F70/F160 ratios.

'''Haze Formation in Planetary Atmospheres: Lessons from the Lab''' <br>
For more than 50 years, haze formation in planetary atmospheres has been simulated in the laboratory. Of particular interest are simulations of haze formation in the atmosphere of Titan, the largest moon of Saturn. These simulation experiments have provided a wealth of knowledge about the possible composition and optical properties of haze particles, informed efforts to understand the transition between gas phase and particle chemistry, and provide “analogue” materials to aid in the selection and testing of the next generation of spacecraft based analytical techniques. In this talk I will review the current state of knowledge from Titan atmosphere simulation experiments, discuss difficulties that have arisen from knowledge gained from the Cassini-Huygens mission to the Saturn system, and present particular areas where laboratory studies could provide much needed guidance for the observation and modeling communities studying atmospheres in our solar system and beyond.
I'm not sure what you are looking for in a bio but the short version is that I have a BS in Planetary Science and a BS in Literature from Caltech. I got my PhD in Planetary Science at the University of Arizona. I was an NSF Astronomy and Astrophysics Postdoctoral Fellow at the University of Colorado-Boulder and I am now an Assistant Professor in the Department of Earth and Planetary Sciences at JHU.

'''Large scale structure formation with the Schrödinger method''' <br>
When describing large-scale structure formation of collisionless dark matter one is interested in the dynamics of a large collection of identical point particles that interact only gravitationally. Via gravitational instability initially small density perturbations evolve into eventually bound structures, like dark matter halos that are distributed along the cosmic web. Even though this problem seems quite simple from a conceptual point of view, no sufficiently general solution of the underlying equation, the collisionless Boltzmann equation coupled to the Poisson equation, is known. Therefore one usually has to resort to N-body simulations which tackle the problem numerically. Analytical methods to describe structure formation are in general based on the dust model which describes cold dark matter as a pressureless fluid characterized by density and velocity. This model works quite well up to the quasi-linear regime but eventually fails when multiple streams form that are especially important for halo formation but lead to singularities in the model. We employ the so-called Schrödinger method, originally proposed by Widrow & Kaiser (1993) as a numerical tool, to develop a model which is able to describe multi-streaming and therefore can serve as theoretical N-body double. As a first application we study the coarse-grained dust model, which is a limiting case of the Schrödinger method, within Eulerian and Lagrangian perturbation theory.

'''Results from "Direct" Metallicity Studies of Metal-poor, Strongly Star-forming Galaxies''' <br>
The chemical enrichment of galaxies, driven by star formation and regulated by gas flows from supernova and cosmic accretion, is a key process in galaxy formation that remains to be understood. The most reliable metallicity determination is made possible by detecting [OIII]4363. The technique is often called the "direct" method for its ability to determine the electron temperature of the ionized gas, and hence the gas-phase metallicity. However, this nebular emission line is intrinsically weak, and thus have not been detected for large samples of galaxies, especially
at higher redshift. In this talk, I will present new results from the detection of [OIII]4363 in two complementary samples of 20--30 metal-poor, strongly star-forming galaxies at z~0.8. The samples are selected from the Subaru Deep Field and the DEEP2 Galaxy Redshift Survey. Together, they represent the largest intermediate redshift sample (N ~ 50) with direct metallicities.

Combining optical spectroscopy with multi-wavelength imaging, I explore the relationship between stellar mass, dust-corrected star formation rate (SFR), and temperature-based gas metallicity. I find that these galaxies are undergoing rapid evolution with stellar mass doubling
times of about 100 Myr, a factor of 10 faster than typical z~1 star-forming galaxies on the star-formation "main sequence." I also find that these galaxies deviate toward lower metallicity on the mass--metallicity relation. Finally, I will discuss these galaxies in context to the mass--metallicity--SFR relation (i.e., the "fundamental metallicity relation"). I will argue that stochastic star formation in these dwarf galaxies results in significant dispersion and the lack of a correlation between stellar mass, metallicity, and SFR.

'''The Initial-Final Mass Relation: Expanding Into Massive White Dwarfs''' <br>
Spectroscopic analysis of white dwarfs is a proven technique to establish their log g, Teff, mass, and cooling age. For white dwarfs in star clusters, a comparison of its cooling age to the cluster turnoff age provides the lifetime and initial mass of the white dwarf's progenitor. This creates the initial-final mass relation (IFMR), which gives a direct measurement of total mass loss for stars and can illustrate its dependence on mass and metallicity. In our project we have first analyzed a broad white dwarf sample (0.7 to 0.95 Msun) from a single solar metallicity cluster, NGC 2099, which greatly limits systematic effects. Comparison to results from the metal-rich Hyades and Praesepe indicates that there is little metallicity dependence in the IFMR at this parameter range. This data also reliably helps to illustrate the nonlinearity of the IFMR, which has important consequences in the interpretation of the poorly understood high-mass white dwarfs (> 1 Msun) of the IFMR. Therefore, our photometric survey of young, rich, and nearby clusters is searching for massive white dwarfs, which are needed to fully understand their progenitor evolution but also to help constrain the lower-mass limit of Type II SNe.

'''The Large-scale Environments of Radio-loud AGN and Their Evolution across Cosmic Time''' <br>

Powerful high redshift radio-loud AGN (RLAGN), are known to preferentially lie in overdense fields and are promising beacons for identifiying large-scale structure and galaxy (proto)-clusters. However, due to the relatively small number of confirmed high-z clusters, it is still challenging to draw a clear picture of their formation and evolution. I will present results of our large Spitzer program, CARLA (Clusters Around Radio-Loud AGN), that has targetd 420 RLAGN at 1.3<z<3.2 for a total of more than 300 hours of Spitzer/IRAC time and that for the first time allows to systematically study the fields of a large sample of powerful RLAGN over a wide redshift range. Studying the density of red color-selected sources shows that ∼200 CARLA fields are rich and compact structures with overdensities established within cells of 0.5 Mpc. The surface density proves that indeed most of the excess sources are associated with the targeted RLAGN. Two CARLA protoclusters have already been spectroscopically confirmed and more observations with KMOS/MUSE/HST are under way. This large (proto-)cluster sample also allows us for the first time at these redshifts, to systematically measure the luminosity function of clusters around RLAGN. Our measurements for m∗ are consistent with passive evolution models and high formation redshifts (z_f ∼ 3). We find a slight trend toward fainter m∗ for the richest clusters, implying that the most massive clusters in our sample could contain older stellar populations. The results are consistent with cosmic downsizing, as the clusters studied here were all found in the vicinity of RLAGNs—which have proven to be preferentially located in massive dark matter halos in the richest environments at high redshift—and they may therefore be older and more evolved systems than the general protocluster population.

'''Orbital Dynamics and the Martian Rock Record''' <br>

Aside from the Earth, Mars is the only object in our solar system known to host an extensive sedimentary rock record. Study of the terrestrial sedimentary record largely drives our understanding of the planet's biological, climatic, and geophysical evolution over time. Likewise, the sedimentary record of Mars has begun to yield clues to that planet's early history, via both remote sensing and in situ analysis from robotic missions. A central objective of the Curiosity rover mission is the search for evidence of past habitable environments at the Martian surface. This talk will highlight recent results and future goals of the Curiosity mission, along with a parallel question: how can we tell time in the Martian rock record? Recent results suggest the widespread preservation in the Martian rock record of repetitive environmental changes induced by cyclic variations in the planet's orbital configuration. These patterns may finally provide a yardstick with which to determine the duration of more habitable climate conditions on early Mars.

'''Effective Potentials and Morphological Transitions for Binary Black-hole Spin Precession''' <br>

Generic binary black holes have spins that are misaligned with their orbital angular momentum. When the binary separation between the black holes is large compared to their gravitational radii, the timescale on which the spins precess is much shorter than the radiation-reaction time on which the orbital angular momentum decreases due to gravitational-wave emission. We use conservation of the total angular momentum and the projected effective spin on the precession time to derive an effective potential for BBH spin precession. This effective potential allows us to solve the orbit-averaged spin-precession equations analytically for arbitrary mass ratios and spins. These solutions are quasiperiodic functions of time: after a precessional period the spins return to their initial relative orientations. We classify black-hole spin precession into three distinct morphologies between which the black holes can transition during their inspiral. Our new solutions constitute fundamental progress in our understanding of black-hole spin precession and also have important applications to astrophysical black holes. We derive a precession-averaged evolution equation that can be numerically integrated on the radiation-reaction time, allowing us to statistically track black-hole spins from formation to merger. This will greatly help us predict the signatures of black-hole formation in the gravitational waves emitted near merger and the distributions of final spins and gravitational recoils.

'''The Observability of Recoiling Black Holes as Offset Quasars''' <br>

The merger of two supermassive black holes (SMBHs) imparts a gravitational-wave (GW) recoil kick to the remnant SMBH, and in extreme cases SMBHs may be ejected from their host galaxies. An accreting, recoiling SMBH may be observable as a spatially or kinematically offset quasar. Prior to the advent of a space-based GW observatory, offset quasars may offer the best evidence of recent SMBH mergers. Indeed, promising candidates have already been identified. However, systematic searches for recoils are hampered by large uncertainties, including how often and in which host galaxies offset quasars should be observable, and whether BH spin alignment prior to merger is efficient at suppressing large recoils. Motivated by this, we have developed a model for recoiling quasars in a cosmological framework, utilizing information about the progenitor galaxies from cosmological hydrodynamic simulations. Varying degrees of BH spin alignment are considered. We find that the observability of offset quasars, and their preferred host galaxies, depend strongly on the efficiency of pre-merger spin alignment, with promising indications that discoveries of recoils could distinguish between at least the extreme limits of spin alignment models. These findings will inform the design of dedicated searches for recoiling quasars.

'''O-type binaries in 30 Doradus: Spectroscopic orbits, fundamental parameters, and distance to this region''' <br>
A key ingredient missing from current formation and evolution theories of massive stars, and of cluster evolution, is a robust binary fraction and the intrinsic distributions of orbital parameters. The VLT-FLAMES Tarantula Survey (VFTS), which targeted 800 O- and B- stars in 30 Dor, was designed to detect most massive binaries with orbital periods < 200 d: the observed O-type binary fraction is 27% (100 binaries). To characterize these binaries, in 2012, Hugues et al. started an observational campaign, Tarantula massive binary monitoring, using the GIRAFFE/VLT/ESO spectrograph. 32 spectra of the sample were collected between 2012 and 2014. Using the radial velocity curves we characterized the orbits of these systems, with the aim of obtaining the first measurements of the orbital period, mass-ratio and eccentricity distributions. For 12 binaries that show ellipsoidal variation and/or eclipse, we derived their fundamental properties, e.g., masses, radii, temperature, etc, and the distance to this region, which is dense and dynamically complex closer to those in super-star-clusters observed beyond the Local Group.

'''The Rich Complexity of 21-cm Fluctuations Produced by the First Stars''' <br>
The 21-cm signal of neutral hydrogen is expected to be the richest three-dimensional probe of the early Universe at the epochs of Reionization and Cosmic Dawn. In this talk I will discuss the latest theoretical predictions for the 21-cm signal from redshifts 7-40. This redshift range includes various epochs of cosmic evolution related to primordial star formation, and should be accessible to existing or planned low-frequency radio telescopes.

'''The Fermi Bubbles: Possible Nearby Laboratory for AGN Jet Activity''' <br>
One of the most important discoveries of the Fermi Gamma-ray Space Telescope is the detection of two giant bubbles extending 50 degrees above and below the Galactic center (GC). The symmetry about the GC of the Fermi bubbles suggests some episode of energy injection from the GC, possibly related to past jet activity of the central active galactic nuclei (AGN). Thanks to the proximity to the GC, the Fermi Bubbles are excellent laboratories for studying cosmic rays (CRs), Galactic magnetic field, and AGN feedback in general. Using three-dimensional magnetohydrodynamic simulations that include relevant CR physics, I will show how leptonic AGN jets can explain the key characteristics of the Fermi bubbles and the spatially correlated features observed in the X-ray, microwave, and radio wavelengths. I will also discuss how we use our simulations in combination with the multi-wavelength data to obtain constraints on the composition of the Fermi bubbles.

'''Jets from Supermassive Black Holes: from Giants to Newborns''' <br>

Why do only 10% of quasar show powerful radio jets? The answer to this question is currently unknown but should involve at least one fundamental property of supermassive black holes (eg, spin or mass) as well as the evolution of their host galaxies. This talk, I will approach the questions of radio loudness from two different angles. First, using the lobes of radio galaxies to study jets on long (> million year) timescales. Second, using the tidal disruption of stars by massive black holes to probe jets on human timescales.

'''Cepheid radial velocity curve modulation impacts Baade-Wesselink distances''' <br>
Classical Cepheids are crucial Galactic and extragalactic distance tracers thanks to the famous period-luminosity relation and carry high weight in the determination of the Hubble parameter. Precise individual Cepheid distances are required to accurately calibrate this relation and in particular its zero-point. The Baade-Wesselink technique enables the determination of precise distances to individual Cepheids in both the Milky Way and the Magellanic Clouds and is thus essential for investigating how metallicity affects the famous Cepheid period-luminosity relation. Here, I will present the recent discovery of modulation in Cepheid radial velocity curves and show that modulation leads to a new, previously ignored, systematic uncertainty for Baade-Wesselink distances. In the worst case, modulation can lead to systematic distance errors as high as 15%. However, modulation may also be the key for improving the precision of Baade-Wesselink distances.

'''The Global Properties of M31’s Stellar Halo: Results from the SPLASH Survey''' <br>
Large surveys of Andromeda's resolved stellar populations have revolutionized our view of this galaxy over the past decade. The combination of large-scale, contiguous photometric surveys and pointed spectroscopic surveys has been particularly powerful for discovering and following up new substructures and disentangling the structural components of Andromeda. The SPLASH survey has now amassed spectra of nearly ten thousand of red giant branch stars in Andromeda's halo, disk, and dwarf galaxies. I will present recent results from the SPLASH survey, focusing on the spatial structure and metallicity gradient of M31’s halo.

'''The formation and evolution of clumpy galaxies from z=3 to z=0.5''' <br>

A common feature of star-forming galaxies at z>1 is the existence of giantstar-forming clumps,which are fundamental to our understanding of the accretionhistory of galaxies, formation of bulges, and evolution of gas-rich disks. Inthis talk, I will present our work on linking high-redshift clumpy galaxies andlow-redshift settled (rotation dominated) disks in three aspects: (1) thephysical properties of high-redshift clumps; (2) the evolution of the fractionof clumpy galaxies from z=3 to z=0.5; and (3) the connection between the clumpyappearance and the kinematics of settled and unsettled disks at z~0.5. Thethree aspects provide important clues of tracing the physical mechanisms thatare responsible for transferring distant clumpy galaxies into disk galaxies seen in the local universe.
