Abstract

The formation of spiral galaxies is an important topic of debate in astrophysics. We use smooth-particle hydrodynamic (SPH) simulations to follow the formation, in a fully ΛCDM cosmological context, of two disk galaxies similar, in mass, to our Milky Way. Using the dynamics of the star particles we are able to identify three distinct components in the stellar budget of our galaxies: a thin disk, a thick disk and a spheroid. We make a detailed analysis of where and when stars in the three different components come about. Our study can help create a more consistent picture of how galaxies similar to our own form.
