We find that SF in dwarf galaxies is quenched only in the high-density environment at the centre of clusters and groups, but that passively evolving massive galaxies are found in all environments, indicating that massive galaxies can become passive via internal processes. The SF-density relation observed for the massive galaxies is weaker relative to the dwarfs, but both show a trend for the fraction of star-forming galaxies (f_SF_) declining to ~0 in the cluster cores. We find that active galactic nucleus activity is also suppressed among massive galaxies residing in the cluster cores.2010MNRAS.404.1745Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/404/1745CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/267 : The SDSS Photometric Catalog, Release 4 (Adelman-McCarthy+, 2006)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/404/1745https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/404/1745http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/404/1745https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/404/1745https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/404/1745http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/404/1745GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/404/1745/table1 (Catalogue of Coma galaxies detected at 24um)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/404/1745/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/404/1745/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/404/1745/table1?GETtext/xml+votable180.050000true194.457428.62430.005555555555555556Cone search capability for table J/MNRAS/404/1745/table3 (Catalogue of dwarf (z>15), k+A [EW(Ha)<2{AA} and EW(Hd)<-3{AA}] galaxies in the Coma supercluster)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/404/1745/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/404/1745/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/404/1745/table3?GETtext/xml+votable180.050000true177.242831.30490.0055555555555555565/2594 2600 6/10272 10381-10382 10404 10406 27965 28075 28125 28127 28142 28149-28152 28154 28157 28241 28243 28249 28251 28253-28254 28264 28273 28276 28376 28416-28417 28426-28427 28429 28436 28446 28449 28471 28494 28500 28517 28526-28527 28557 28560 285726.772611666688002e-21 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/404/1745?format=asciiOpticaldefaultJ/MNRAS/404/1745/table1Catalogue of Coma galaxies detected at 24umrecnoRecord number assigned by the VizieR team.
