Cusps, cores and baryons: Or how Cold Dark Matter is the worst model of galaxy formation, except for all the others
Fabio Governato



I will show results from cosmological simulations of galaxy formation where small, repeated gas outflows remove low angular momentum gas and transfer energy to the DM. This process helps solving 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.
