Abstract (from CDS):

The purpose of this work is to make available new gas-phase oxygen abundance measurements for a serendipitous sample of 27 galaxies with redshifts 0.35≤z≤0.52. We measured the equivalent widths of the [OII]λ3727, Hβ, and [OIII]λλ4959, 5007 emission lines observed in the galaxy spectra obtained with the Visible Multi-Object Spectrograph mounted at the Very Large Telescope. For each galaxy, we derived the metallicity-sensitive emission-line ratio R23, ionization-sensitive emission-line ratio O32, and gas-phase oxygen abundance 12+log(O/H). The values of the gas-phase oxygen abundance 12+log(O/H) that we obtained for all the sample galaxies are consistent with previous findings for galaxies at intermediate redshift.
