cds-question@unistra.frgalaxy-clustersgalaxy-kinematicschemical-abundancesvisible-astronomysloan-photometryultraviolet-photometryWe present and analyse optical and ultraviolet (UV) colours for passive and optically-red Coma cluster galaxies for which we have spectroscopic age and element abundance estimates. Our sample of 150 objects covers a wide range in mass, from giant ellipticals down to the bright end of the dwarf-galaxy regime. Galaxies with ongoing star formation have been removed using strict H{alpha} emission-line criteria. We focus on the colours FUV-i, NUV-i, FUV-NUV, u*-g and g-i. We find that all of these colours are correlated with both luminosity and velocity dispersion at the >5{sigma} level, with FUV-i and FUV-NUV becoming bluer with increasing 'mass' while the other colours become redder. We perform a purely empirical analysis to assess what fraction of the variation in each colour can be accounted for by variations in the average stellar populations, as traced by the optical spectra.2012MNRAS.421.2982Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/421/2982CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/392/1265 : Coma cluster faint red galaxies spectroscopy (Smith+, 2009)J/MNRAS/411/2558 : Coma cluster galaxies absorption-line indices (Price+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/421/2982https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/421/2982http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/421/2982https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/421/2982https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/421/2982http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/421/2982GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/421/2982/galaxies (Galaxy properties and 10" diameter aperture magnitudes used in the analysis of Section 3 (tables 1 and 2 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/421/2982/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/421/2982/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/421/2982/galaxies?GETtext/xml+votable180.050000true193.52327.06861110.0055555555555555565/2600 6/10377-10380 10382-10383 10404 28127 281492.381800341673347e-19 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/421/2982?format=asciiUVOpticaldefaultJ/MNRAS/421/2982/galaxiesGalaxy properties and 10" diameter aperture magnitudes used in the analysis of Section 3 (tables 1 and 2 of the paper)recnoRecord number assigned by the VizieR team.
