cds-question@unistra.frgalaxy-clustersgalaxiesspectroscopymetallicitystellar-massessurveysWe present the stellar mass-stellar metallicity relationship (MZR) in the galaxy cluster Cl0024+1654 at z~0.4 using full-spectrum stellar population synthesis modeling of individual quiescent galaxies. The lower limit of our stellar mass range is M*=10^9.7^M_{sun}_, the lowest galaxy mass at which individual stellar metallicity has been measured beyond the local universe. We report a detection of an evolution of the stellar MZR with observed redshift at 0.037+/-0.007dex per Gyr, consistent with the predictions from hydrodynamical simulations. Additionally, we find that the evolution of the stellar MZR with observed redshift can be explained by an evolution of the stellar MZR with the formation time of galaxies, i.e., when the single stellar population (SSP)-equivalent ages of galaxies are taken into account. This behavior is consistent with stars forming out of gas that also has an MZR with a normalization that decreases with redshift. Lastly, we find that over the observed mass range, the MZR can be described by a linear function with a shallow slope ([Fe/H]{propto}(0.16+/-0.03)logM*). The slope suggests that galaxy feedback, in terms of mass-loading factor, might be mass-independent over the observed mass and redshift range.2018ApJ...856...15Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/856/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/232 : STELIB: A library of stellar spectra at R~2000 (Le Borgne+, 2003)J/A+A/372/391 : Spectroscopic Survey of Cl 0024+1654 (Czoske+, 2001)J/ApJ/591/53 : I photometry of Cl 0024+16 (Treu+, 2003)J/AJ/126/2644 : CL 0024+1654 UBVI photometry (Alexov+, 2003)J/AJ/127/2002 : Star Formation Rate of NFGS galaxies (Kewley+, 2004)J/ApJ/634/977 : Redshifts in Cl 0024+16 members (Moran+, 2005)J/MNRAS/371/703 : MILES library of empirical spectra (Sanchez-Blazquez+, 2006)J/ApJ/665/1067 : Velocities in Cl 0024+16 and MS 0451-03 (Moran+, 2007)J/ApJ/659/1138 : Intermediate-redshift spiral galaxies Vmax (Moran+, 2007)J/ApJ/671/1503 : Cl 0024+16 and MS 0451-03 spectrophotometry (Moran+, 2007)J/MNRAS/404/1639 : MILES base models & new line index system (Vazdekis+, 2010)J/ApJS/200/8 : AGES: the AGN and Galaxy Evolution Survey (Kochanek+, 2012)J/MNRAS/432/3141 : Morphological classification of PM2GC gal.
