ABSTRACT:

I will present hydrodynamical simulations of the formation of dwarf 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. I will compare the properties of our objects with observed dwarf galaxies and results from other simulations. I will also discuss the possible role of feedback from massive starts in shaping the star formation, the structure of the interstellar medium (ISM) and the dark matter halos associated with these objects.
