Abstract: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 final 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 efficiency 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.
