We present the results of a fossil record technique study using MaNGA and CALIFA galaxies showing the chemical enrichment history (ChEH) as well as how the mass-metallicity relation (MZR) has changed.
In order to analyze how the evolution of these relations correlates with the properties of the galaxy we separate the sample into mass, morphology and star-forming status bins, finding a strong dependence on the mass and the morphology, and dependence on the star-forming status that is more subtle after accounting for the correlation between morphology and star-forming status. We also measure the ChEH and MZR at different galactocentric radii, finding the effects of local downsizing as well as an inversion of the metallicity gradient for low mass galaxies.
