Title: Chemical Evolution of Galaxies in the High Redshift Universe Author(s): Maria Emilia De Rossi Abstract: In the last decade, the important progress in observational techniques allows the exploration of the chemical enrichment of galaxies in the high redshift Universe. In particular, Maiolino et al. (2008) found that the mass-metallicity relation was already in place at z=3.5, exhibiting the same general patterns than the Local relation but displaced towards lower abundances. In the light of these results, it is indispensable to develop theoretical models which would provide clues for the understanding of the chemical enrichment of galaxies in the early Universe. In this work, we studied the chemical evolution of baryons at high z by performing numerical simulations in a cosmological framework. We focus mainly of the origin and evolution of the mass-metallicity relation.
