The study of the chemical enrichment of galaxies and its relation with other global properties of these systems, such as total stellar mass or gas fraction, can provide important constraints on galaxy formation models. In particular, over the last decades, different research projects have focused on the analysis of the mass-metallicity relation (MZR) and its evolution with redshift. In this work, we analyse the MZR since redshift z=3 by using the recent EAGLE (Evolution and Assembly of GaLaxies and their Environments) simulations. We investigate the evolution and scatter of the simulated MZR. We explore also possible dependences of this relation on secondary parameters. These results are compared with previous findings obtained by using GIMIC (Galaxies-Intergalactic Medium Interaction Calculation) suite of cosmological simulations (De Rossi et al. 2015).
