'''[http://www.sciencemag.org/content/early/2015/08/12/science.aac5891 Discovery and spectroscopy of the young Jovian planet 51 Eri b with the Gemini Planet Imager]'''

Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation mechanism. Using the Gemini Planet Imager, we discovered a planet orbiting the ~20 Myr-old star 51 Eridani at a projected separation of 13 astronomical units. Near-infrared observations show a spectrum with strong methane and water vapor absorption. Modeling of the spectra and photometry yields a luminosity of L/L⦿=1.6-4.0 × 10−6 and an effective temperature of 600-750 K. For this age and luminosity, “hot-start” formation models indicate a mass twice that of Jupiter. This planet also has a sufficiently low luminosity to be consistent with the “cold-start” core accretion process that may have formed Jupiter.

'''Oscillations in the CMB bispectrum '''

Oscillating signatures in the correlation functions of the primordial density perturbations are predicted by a variety of inflationary models. A theoretical mechanism that has attracted much attention in recent years is a periodic shift symmetry in the inflaton potential, which allows to protect large field models from quantum corrections, as implemented in axion monodromy inflation. This symmetry leads to so called resonance non-gaussianities, whose key feature are logarithmically stretched oscillations in the power spectrum and bispectrum. Oscillations are also a generic consequence of excited (non Bunch-Davies) states during inflation. A number of possible excited states have been proposed, leading to a variety of possible power spectrum and bispectrum shapes. As a third example, sharp features in the potential induce oscillations as the inflaton relaxes back to its attractor solution. Oscillating shapes are therefore a very interesting experimental target.
After giving an overview of these theoretical motivations, I will discuss how to search for these signatures in the CMB data. Fast oscillations are very difficult to search for with traditional estimation techniques, and I will demonstrate how targeted expansions, that exploit the symmetry properties of the underlying shapes, allow to circumvent these difficulties. As a member of the Planck collaboration, I will discuss the Planck results that have been obtained using these methods in the bispectrum, as well as a joint search combining bispectrum and power spectrum. Due to their low overlap with well constrained non-gaussian shapes, as well as their low overlap among each other, oscillating bispectrum shapes are not exhaustively constrained and a potential discovery is therefore not yet ruled out.
My talk will be based in particular on arxiv:1412.3461, arxiv:1505.05882 and Planck publications on inflation and non-gaussianities.
