Cusps, Cores and Baryons: Or How Cold Dark Matter Is the Worst Model of Galaxy Formation, Except for All the Others
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. II will then discuss the existing challenges to
CDM in the context of alternative models to Cold Dark Matter as WDM and SIDM.
