Physics Colloquium

Searching for Dark Matter Interactions throughout Cosmic History
Kim Boddy, UT Austin,

Understanding the fundamental nature of dark matter is one of the major challenges facing the physics community today. Direct and indirect detection efforts search for dark matter interactions with the Standard Model of particle physics, but no concrete evidence of such interactions has been observed. In this talk, I will demonstrate how cosmological observables provide complementary information to these dedicated searches. I will describe the effects of dark matter scattering in the early Universe and show constraints using data from the cosmic microwave background and the abundance of Milky Way satellites. Additionally, I will discuss the potential of upcoming large-scale surveys for further investigations of dark matter physics.
