Abstract:
In this talk, I will discuss recent work on self-interacting dark matter and its implications within the context of the latest observations of galactic systems, as well as high-resolution N-body simulations of cosmic structure formation. I will highlight the novel signatures of gravothermal collapse in dark matter halos, which represent a unique prediction that arises if dark matter possesses strong self-interactions.
