cds-question@unistra.frgalaxiesWe examine a magnitude limited (M_B_=<-18.7) sample of post-starburst (PSB) galaxies at 0.03<z<0.11 in the different environments from the spectroscopic data set of the Padova Millennium Galaxy Group Catalogue and compare their incidence and properties with those of passive (PAS) and emission line galaxies (EML). PSB galaxies have a quite precise lifetime (<1-1.5Gyr), and they hold important clues for understanding galaxy evolution. While the properties (stellar mass, absolute magnitude, colour) of PSBs do not depend on environment, their frequency increases going from single galaxies to binary systems to groups, both considering the incidence with respect to the global number of galaxies and to the number of currently+recently star-forming galaxies. Including in our analysis, the sample of cluster PSBs drawn from the WIde-field Nearby Galaxy-cluster Survey presented in Paccagnella et al. (2017ApJ...838...14M), we extend the halo mass range covered and present a coherent picture of the effect of the environment on galaxy transformations. We find that the PSB/(PSB+EML) fraction steadily increases with halo mass going from 1 per cent in 10^11^M_{sun}_ haloes to ~15 per cent in the most massive haloes (10^15.5^_sun}_). This provides evidence that processes specific to the densest environments, such as ram-pressure stripping, are responsible for a large fraction of PSB galaxies in dense environments. These processes act on a larger fraction of galaxies than alternative processes leading to PSB galaxies in the sparsest environments, such as galaxy interactions.2019MNRAS.482..881Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/482/881CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/482/881https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/482/881http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/482/881https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/482/881https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/482/881http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/482/881GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/482/881/tablea1 (Halo mass catalogue of 176 galaxy groups with their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/482/881/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/482/881/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/482/881/tablea1?GETtext/xml+votable180.050000true170.3258-0.20970.005555555555555556Cone search capability for table J/MNRAS/482/881/tablea2 (Halo mass catalogue of 245 binary systems with their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/482/881/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/482/881/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/482/881/tablea2?GETtext/xml+votable180.050000true170.5439167-0.23105560.005555555555555556Cone search capability for table J/MNRAS/482/881/tablea3 (Halo mass catalogue of 1141 single galaxies with their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/482/881/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/482/881/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/482/881/tablea3?GETtext/xml+votable180.050000true215.9539058-0.24833470.0055555555555555565/6489-6490 6501 6505-6506 6549-6550 6553-6554 6565-6566 6569-6570 6741-6742 6745-6746 6757-6758 6761-6762 6805-6806 6809 6/25599 25855 25919 25935 25944-25946 25955 25964 25968 25999 26003 26008-26010 26012 26019 26028 26048 26175 26191 26195 26204 26211 26220 26224 26255 26259 26268 26275 26284 26288 26304 26368 26879 26943 26959 26963 26972 26979 26988 26992 27023 27027 27036 27043 27052 27056 27072 27215 27219 27228 27248 27392 27648https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/482/881?format=asciidefaultJ/MNRAS/482/881/tablea1Halo mass catalogue of 176 galaxy groups with their propertiesSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
