Shining Light on the Properties of Dark Matter: Coupling Baryon and Dark Matter Physics in Galaxy Formation Models

Fabio Governato, Research Professor, Astronomy Department, University of Washington,

I will show results from cosmological simulations of galaxy formation where repeated gas outflows remove low angular momentum gas and transfer energy to the DM. This process solves three long lasting problems in galaxy formation: the substructure overabundance, the existence of bulgeless galaxies, and the presence of ubiquitous DM 'cores' at the center of
dwarf field galaxies. I will then discuss the existing challenges to CDM in the context of alternative models to Cold Dark Matter as WDM and SIDM.
