cds-question@unistra.frgalaxy-clustersgalaxiescatalogsspectroscopyWe investigate the stellar populations in a sample of 89 faint red galaxies in the Coma cluster, using high signal-to-noise ratio (S/N) spectroscopy from the 6.5-m MMT. Our sample is drawn from two 1{deg} fields, one centred on the cluster core and the other located 1{deg} to the south-west of the cluster centre. The target galaxies are mostly 2-4mag fainter than M*; galaxies with these luminosities have been previously studied only using small samples, or at low S/N. For a comparison sample we use published high-S/N data for red-sequence galaxies in the Shapley supercluster. We use state-of-the-art stellar population models (by R. Schiavon, Cat. <J/ApJS/171/146>) to interpret the absorption-line indices and infer the single-burst-equivalent age and metallicity (Fe/H) for each galaxy, as well as the abundances of the light elements Mg, Ca, C and N.2009MNRAS.392.1265Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/392/1265CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/42 : GMP catalogue: galaxies in the Coma cluster (Godwin+ 1983)J/MNRAS/381/1035 : Spectroscopy in Shapley supercluster (Smith+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/392/1265https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/392/1265http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/392/1265https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/392/1265https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/392/1265http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/392/1265GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/392/1265/coma (the Coma dwarf galaxy sample: Absorption-line index data and derived parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/392/1265/coma?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/392/1265/coma?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/392/1265/coma?GETtext/xml+votable180.050000true194.1526.9047220.005555555555555556Cone search capability for table J/MNRAS/392/1265/shapley (the Shapley sample: stellar population parameters from EZ-AGES)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/392/1265/shapley?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/392/1265/shapley?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/392/1265/shapley?GETtext/xml+votable180.050000true200.870417-31.7116670.0055555555555555566/10378-10379 10400-10401 28127 43835-438382.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/392/1265?format=asciiOpticaldefaultJ/MNRAS/392/1265/comathe Coma dwarf galaxy sample: Absorption-line index data and derived parametersS/NSignal-to-noise ratio (3)stat.snrintrecnoRecord number assigned by the VizieR team.
