cds-question@unistra.frgalaxy-clustersgalaxiescatalogsgalaxy-classification-systemsradial-velocityWe present a photometric catalogue of compact groups of galaxies (p2MCGs) automatically extracted from the Two-Micron All Sky Survey (2MASS) extended source catalogue. A total of 262 p2MCGs are identified, following the criteria defined by Hickson, of which 230 survive visual inspection (given occasional galaxy fragmentation and blends in the 2MASS parent catalogue). Only one quarter of these 230 groups were previously known compact groups (CGs). Among the 144 p2MCGs that have all their galaxies with known redshifts, 85 (59%) have four or more accordant galaxies. This v2MCG sample of velocity-filtered p2MCGs constitutes the largest sample of CGs (with N>=4) catalogued to date, with both well-defined selection criteria and velocity filtering, and is the first CG sample selected by stellar mass. It is fairly complete up to K_group_~9 and radial velocity of ~6000km/s.2012MNRAS.426..296Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/426/296CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)VII/74 : Atlas of Peculiar Galaxies (Arp 1966)VII/77 : Isolated Pairs of Galaxies in Northern HemisphereVII/83 : Isolated Triplets of galaxies (Karachentseva+ 1988)VII/170 : Catalogue of Southern Peculiar Galaxies and AssociationsVII/213 : Hickson's Compact groups of Galaxies (Hickson+ 1982-1994)VII/236 : Interacting galaxies catalogue (Vorontsov-Velyaminov+, 2001)J/AJ/118/2014 : Nearby poor clusters of galaxies catalog (White+, 1999)J/AJ/123/2976 : The UZC-SSRS2 group catalog (Ramella+, 2002)J/A+A/445/857 : DPOSS II compact group survey (Pompei+, 2006)J/A+A/539/A106 : DPOSS II compact group survey.
