Physical properties of galaxies and their evolution in the VIMOS VLT Deep Survey. II. Extending the mass-metallicity relation to the range z=0.89-1.24
E. Perez-Montero et al, arXiv:0811.2085v1 [astro-ph]

Did they really need to split this into two papers? But anyway, they conclude that their results are consistent with the Tremonti et al (2004) interpretation: low mass galaxies lose metal, while high mass galaxies experience effectively closed box chemical evolution.
