Resumen:
We report preliminary results on a study of the effects of supernova feedback on galaxy chemical enrichment using cosmological hydrodynamical simulations. Both simulations produce galaxies with disc systems which form inside out, in agreement with current theories of galaxy formation. We find that the simulated discs have metallicity gradients in global agreement with observed ones. We also find a weak trend for galaxies with relatively steep gradients at z ~1 to have slightly shallow gradients at z~0.
