Resum

I will present hydrodynamical simulations of the formation of galaxies starting from cosmological initial conditions at high redshift. In these simulations, a novel numerical implementation of stellar feedback resulting from momentum imparted to the ISM by radiation, supernovae,and stellar winds has been used. Our ?nal objects have structure and stellar populations consistent with observed galaxies. Results indicate that feedback from massive stars plays a critical role in shaping the galaxy mass function, the structure of the interstellar medium (ISM), and the low e?ciency of star formation. I will focus the last part of my talk on the properties of the dwarf galaxies halos in the FIRE sample and its comparison with observations.
