Wine and Cheese Spring 2020

This page records the schedule, titles and abstracts of the JHU/STScI CAS Astrophysics Wine & Cheese Series in Spring 2020.

Wine and Cheese sessions with one talk will have a 50 minute talk with 10 minutes for questions. Sessions with two speakers will have two 25 minute talks, each with 5 minutes for questions. Sessions in the Graduate Student Series will have three 15 minute talks, each with 5 minutes for questions.

Deprojecting Astronomical Sky Maps
We see the sky in 2D but, in order to conduct astrophysical studies, we need 3D information. I will show how to take any large-scale map of the sky, at any wavelength, and extract 3D extragalactic information from it using clustering measurements. I will then apply this technique to observations of galaxies and diffuse components across the electromagnetic spectrum.

Synergies Between IFU and Molecular Gas Surveys The internal structure of galaxies harbors important clues of the processes that shape their evolution. The last several years have seen the completion of a number of galaxy surveys using Integral Field Units that produce complete spectroscopic mapping at optical wavelengths (MaNGA, CALIFA, SAMI). Those data have produced invaluable information about the stellar and ionized gas components of galaxies. Information about the neutral and molecular phases of the gas, the largest gas reservoirs, has however historically lagged behind. I will present some results from EDGE-CALIFA, a follow up of 126 CALIFA galaxies in CO emission that is currently starting to be expanded with ALMA, and I will discuss future prospects with existing and planned instruments, in particular the ngVLA (a proposal to the Astro2020 Decadal).

```The Hard X-ray View of Nearby Galaxies with NuSTAR NuSTAR is the world's first focusing hard X-ray telescope, allowing unprecedented access to the sky above 10 keV. Thanks to its sensitivity and spatial resolution, we are now able to resolve individual X-ray binaries in nearby galaxies and study their populations. X-ray binaries had traditionally been classified via their companion stars, e.g. high-mass or low-mass counterparts. With NuSTAR, we can identify them by their compact objects as black holes or neutron stars and study their accretion states in detail. We have now amassed enough information on X-ray binaries in nearby galaxies with NuSTAR to compare the compact object population to properties of their host galaxies including their mass, star-formation activity, and morphology.
