Abstract

We present a hydrodynamical code based on the smoothed particle hydrodynamics (SPH) technique implemented in an APSM code that is aimed at solving the hydrodynamical and gravitational equations in a cosmological frame. We analyse the ability of the code to reproduce standard tests and perform numerical simulations to study the formation of galaxies in a typical region of a cold dark matter (CDM) model. These numerical simulations include gas and dark matter particles and take into account physical processes such as shock waves, radiative cooling and a simplified model of star formation. We analyse the astrophysical properties of the galactic objects in different models.
