In this work we study how the distribution of chemical abundance observed in the interstellar medium correlates with cold molecular gas for galaxies in the local Universe using the combination of the integral field spectroscopy of CALIFA with spatially resolved molecular gas data provided by the EDGE survey to understand physical processes that resulted in the chemical distribution observed in galaxies in the context of extended objects.
As the first step, using the integrated properties from these datasets we determine the best fit to integrated mass-metallicity relation (MZR) for more than 800 galaxies. By exploring the residuals of the MZR against global properties of the galaxies (e.g., stellar mass, molecular mass, morphology, SFR), we quantify the possible existence of secondary relations of the MZR with different galaxy's parameters. This exploration is a fundamental step towards the chemical evolutionary modeling of galaxies in the nearby Universe.
