In particular, we analyze a set of zoom-in cosmological hydrodynamical simulations centered on twelve clusters and carried out with the GADGET-3 TreePM/SPH code. We find that simulated central galaxies produce an excess of stars at z=0, however at z∼2 simulations under-predict the normalization of the relation SFR-stellar mass of star forming galaxies by a factor of about 3 and are unable to reproduce the observed starburst population. We conclude that the adopted sub-grid model for star formation (Springel & Hernquist 2003), introduced to reproduce the self-regulated evolution of quiescent galaxies, is not suitable to describe violent events like high-redshift starbursts, independently of the choice of the parameters for the star formation and active-galactic-nuclei models.
