Abstract:
We want to derive the mass-metallicity relation of star-forming
galaxies up to z∼0.9, using data from the VIMOS VLT Deep Survey. The
mass-metallicity relation is commonly understood as the relation
between the stellar mass and the gas-phase oxygen abundance.
Automatic measurement of emission-line fluxes and equivalent widths
have been performed on the full spectroscopic sample of the VIMOS VLT
Deep Survey. This sample is divided into two sub-samples depending on
the apparent magnitude selection: wide (IAB<22.5) and deep
(IAB<24). These two samples span two different ranges of stellar
masses. Emission-line galaxies have been separated into star-forming
galaxies and active galactic nuclei using emission line ratios. For
the star-forming galaxies the emission line ratios have also been used
to estimate gas-phase oxygen abundance, using empirical calibrations
renormalized in order to give consistent results at low and high
redshifts. The stellar masses have been estimated by fitting the whole
spectral energy distributions with a set of stellar population
synthesis models.
Description:
This catalog gives emission-line measurements and spectral indices for
galaxies observed in the VIMOS/VLT Deep Survery (VVDS), together with
derived physical properties such as stellar masses and metallicities.
