Aula Conversi (Dip. di Fisica - Edificio G. Marconi)

The existence of dark matter was first postulated by exploring the velocities of stars within galaxies, as well as the velocities of galaxies themselves, within galaxy clusters. This talk will review the evidence for dark matter that comes from studying galaxies, with a particular emphasis on the role of modern cosmological simulations, and look at constraints that can be placed on the properties of dark matter. The 'cusp/core', 'missing satellite', and 'too big to fail' problems of Cold Dark Matter cosmology will be explained and adressed.
