Title:
Signatures of strong dark matter self-interactions

Speaker:
Hai-Bo Yu

Abstract:
If dark matter particles have strong self-interactions, dark matter halos could experience gravothermalcollapse, resulting in an extremely high density. In this talk, I will discuss recent work on high-resolution cosmological simulations that capture this process, and a mechanism that the collapsed halo provides a massive seed for supermassive black holes. I will further discuss observational tests with data from satellite galaxies of the Milky Way and high-redshift galaxies discovered by JWST.
