The structure of halos as a probe of Cosmology, Dark matter and galaxy evolution; google meet link: meet.google.com/mnd-esvh-oxs

Susmita Adhikari

Stanford University, USA

The distribution of matter in a dark matter halo contains information about the history of its growth. In this talk, I will discuss the recent theoretical developments on how the overall matter distribution and a feature in the outskirts called the splashback radius can be used to test the nature of gravity and dark matter models. I will also talk about the recent observational developments in measuring the distribution of galaxies and matter around the splashback radius in massive galaxy clusters in  DES, SPT and ACT and what we learn about the evolution of galaxies from it.
