Abstract: High resolution cosmic microwave background (CMB) experiments provide views of the Universe both at redshift ~1100, when the primary CMB was produced, as well as an integrated view of the Universe between then and now, through CMB secondary anisotropies. CMB secondary anisotropies provide a way to directly map the distribution of mass, electron density, electron pressure and electron temperature in the Universe. In this talk, I will present recent measurements from the Atacama Cosmology Telescope collaboration that have mapped out some of these properties. I will then show how upcoming CMB experiments will be able to measure new observable signatures of galaxy groups, and how these can be used to inform our understanding of the thermodynamics of these objects.
Bio: Will Coulton's research focuses on using novel statistical tools to analyze cosmological datasets. His recent work has focused on two areas. First, he searches for novel observational signatures of primordial physics in the distribution of galaxies. Second, Will works on isolating diverse astrophysical signals from cosmic microwave background datasets and using them to study the physics of galaxy groups and clusters.
