Cosmological Probes of Dark Matter Physics

Event Details

There is a substantial effort in the physics community to understand the nature of dark matter and to search for dark matter interactions with the Standard Model of particle physics. Collisions between dark matter particles and baryons exchange heat and momentum in the early Universe, enabling a search for dark matter interactions using cosmological observations in a parameter space that is complementary to that of direct detection. In this talk, I will describe the effects of scattering in cosmology, show constraints using Planck 2015 data and SDSS-identified satellites, and discuss the implications of late-time scattering during the era of Cosmic Dawn.
