VizieR Online Data Catalog: Evolu. star mass-metallicity relation. II. (Leethochawalit+, 2019)

In Paper I, we presented a stellar mass-metallicity relation (MZR) based on quiescent galaxies from the galaxy cluster Cl0024+17 at z=0.39. In this paper, we expand the sample by including additional quiescent galaxies from the galaxy cluster MS0451 at z=0.54.

The survey provides UV to near-infrared imaging and ground-based optical spectroscopy of member galaxies up to ~10Mpc in diameter centered on both clusters. The available photometric bands are near-UV and far-UV (FUV) from the Galaxy Evolution Explorer (GALEX) satellite, BVRI bands from the 3.6m Canada-France-Hawaii Telescope (Cl0024) and the Subaru 8m telescope (MS0451), F814W (~I band) from Hubble Space Telescope, and J and Ks bands from the WIRC camera on the Palomar/Hale 200" telescope.

The spectroscopic data for both Cl0024 and MS0451 were obtained with the DEIMOS spectrograph on the Keck II Telescope. Most data are part of the original survey. We obtained additional DEIMOS spectroscopy to enhance the signal-to-noise ratio (S/N) of a subset of the galaxy spectra in MS0451. (R=2000 at ~3500 to 6000Å).
