Formation and Evolution of Galaxies



Analytical modeling of galaxy formation

AMIGA (Analytical Model for IGM and GAlaxy evolution) has been developed to follow precisely the evolution of galaxies taking into account their internal structure in a detailed way and the effect of galaxy interactions, as well as feedback processes, from reliable initial conditions starting at redhifts greater than 30. Thus, it is a useful tool specially designed to analize the whole process of galaxy formation and evolution in a cosmological context.

We use the AMIGA model in the study of galaxy formation and evolution. In particular, to study the first events of star formation and their effects on the intergalactic medium, and the evolution of the properties of different galactic populations at different redshifts (luminosities, colors, sizes, bulge-disk relationship, morphological segregations in clusters, correlations between properties of galaxies and AGNs)
