cds-question@unistra.frgalaxy-clustersgalaxy-classification-systemsWe study the galaxy stellar mass function in different environments in the local Universe, considering both the total mass function and that of individual galaxy morphological types. We compare the mass functions of galaxies with log_10_M*/M_{sun}_>=10.25 in the general field and in galaxy groups, binary and single galaxy systems from the Padova-Millennium Galaxy and Group Catalogue at z=0.04-0.1 with the mass function of galaxy clusters of the WIde-field Nearby Galaxy-Cluster Survey at z=0.04-0.07. Strikingly, the variations of the mass function with global environment, overall, are small and subtle. The shapes of the mass functions of the general field and clusters are indistinguishable, and only small, statistically insignificant variations are allowed in groups. Only the mass function of our single galaxies, representing the least massive haloes and comprising less than a third of the general field population, is proportionally richer in low-mass galaxies than other environments. The most notable environmental effect is a progressive change in the upper galaxy mass, with very massive galaxies found only in the most massive environments. This environment-dependent mass cut-off is unable to affect the Schechter parameters and the Kolmogorov-Smirnov test, and can only be revealed by an ad hoc analysis. Finally, we show how, in each given environment, the mass function changes with morphological type, and that galaxies of the same morphological type can have different mass functions in different environments.2013MNRAS.432.3141Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/432/3141CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/240 : Millennium Galaxy Catalogue (Liske+, 2003)J/MNRAS/416/727 : Padova-Millennium Galaxy and Group Catalogue (Calvi+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/432/3141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/432/3141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/432/3141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/432/3141https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/432/3141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/432/3141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/432/3141/table7 (Catalogue of the morphological classification of all galaxies in the PM2GC sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/3141/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/3141/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/3141/table7?GETtext/xml+votable180.050000true155.9535417-0.17091670.0055555555555555565/6489-6490 6501 6505-6506 6549-6550 6553-6554 6565-6566 6569-6570 6741-6742 6745-6746 6757-6758 6761-6762 6805-6806 6809 6/11833 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/432/3141?format=asciiOpticaldefaultJ/MNRAS/432/3141/table7Catalogue of the morphological classification of all galaxies in the PM2GC samplerecnoRecord number assigned by the VizieR team.
