Chemical evolution of milky way type galaxies in the millennium simulation

In this work we make use of the Millennium Run, which is at the moment the largest high-resolution simulation of structure formation ever carried out, combined with the semi-analytical model of De Lucia & Blaizot (2007), to follow the chemical evolution of Milky Way type galaxies with the aim at...
