AMIGA: A New Model of Galaxy Formation and Evolution

  • A. Manrique
Conference paper

Models of galaxy formation and evolution have become a fundamental tool to understand the observed properties of galaxies in a cosmological framework. They follow the evolution of the baryonic gas trapped in dark-matter halos as these grow hierarchically. Although they have improved during the last decade, current models still have limitations regarding the dynamical range and CPU time in numerical simulations or the resolution of merger trees in semianalytical models. AMIGA is an analytical model based on an interpolation grid that includes all the relevant halo masses and reaches high redshifts. This feature allows one to study in a self-consistent way the coupled evolution of galaxies and intergalactic medium (IGM) and the effects of a primordial stellar population (Pop III). The predictions of AMIGA are, in general, satisfactory and better than those of previous models.
