The mass-metallicity relation revisited with CALIFA. (2017)

Keywords : techniques spectroscopic - galaxies: abundances - galaxies: evolution - galaxies: ISM

Abstract:We present an updated version of the mass-metallicity (MZ) relation using integral field spectroscopy data obtained from 734 galaxies observed by the CALIFA survey. These unparalleled spatially resolved spectroscopic data allow us to determine the metallicity at the same physical scale (R_e_) for different calibrators. We obtain MZ relations with similar shapes for all calibrators, once the scalefactors among them are taken into account. We do not find any significant secondary relation of the MZ relation with either the star formation rate (SFR) or the specific SFR for any of the calibrators used in this study, based on the analysis of the residuals of the best-fitted relation. However, we do see a hint for an ...(more)

The analysed sample comprises all the galaxies with good quality spectroscopic data observed with the low resolution setup (V500) by the CALIFA survey (Sanchez et al., 2012A&A...538A...8S) and by a number of CALIFA-extensions listed in Sanchez et al. (2016, Cat. J/A+A/594/A36) up to 2016 October 9. It includes the 667 galaxies from the 3rd CALIFA Data Release (Sanchez et al. 2016, Cat. J/A+A/594/A36), and in addition we include those galaxies with good quality data excluded from DR3 because either they did not have SDSS-DR7 imaging data (a primary selection for DR3) or they were observed after the final sample was closed (i.e. after 2015 November). The final sample comprises a total of 734 galaxies.
