We analyze the effective yields of galaxies extracted from the EAGLE(Evolution and Assembly of GaLaxiesand their Environments) suite of cosmological hydrodynamicalsimulations. We explore the impact of supernova and active galacticnuclei feedback processes over simulated effective yields, for aredshift range since z = 3 to z = 0. We analyze different scalingrelations associated with effective yields, such as their dependencewith the baryonic mass of galaxies and the virial mass of the haloswhere they reside. Our results indicate that effective yields aregood tracers of feedback processes at least since z = 3; therefore,they could be used in observational studies to derive the role offeedback during the evolution of galaxies of different masses and atdifferent redshifts.
