EPP Theory Seminar: Chih-Liang Wu: Diversity in density profiles of self-interacting dark matter satellite halos



Self-interacting Dark Matter (SIDM) could have a number of striking observable effects, including modifications to the dark matter density on galactic and sub-galactic scales. Recent studies have revealed both ultra-compact and ultra-diffuse satellite dwarf galaxies within the Milky Way; I will show that tidal stripping of SIDM satellite halos naturally leads to a wider range of halo density profiles, potentially explaining these observations.
