Impacto de la retroalimentación de supernovas en la evolución de la relación masa-metalicidad
Abstract
We use the semi-analytic model of galaxy formation and evolution with one of the MultiDark simulations to study the evolution of the mass-metallicity relation (MZR). We analyse the impact of different implementations of the supernova (SN) feedback. We find an evolution of the MZR only when an explicit dependence on redshift is introduced as . This dependence was first suggested by the hydrodynamic simulations FIRE, designed to model SN feedback in small scales. An increasing value of the index has the effect of producing a more pronounced MZR evolution. We find that the value allows our model to reproduce the MZR evolution observed at .
