Compact Groups of Galaxies selected by stellar mass: The 2MASS Compact Group Catalogue

Abstract

We present a photometric catalogue of compact groups of galaxies (p2MCGs) automatically extracted from the 2MASS extended source catalogue. A total of 262 p2MCGs are identified, following the criteria of Hickson (1982), of which 230 survive visual inspection. Only 1/4 of these groups were previously known compact groups (CGs). Among the 144 p2MCGs that have all their galaxies with known redshifts, 85 have 4 or more accordant galaxies. This v2MCG sample of velocity-filtered p2MCGs constitutes the largest sample of CGs catalogued to date, with both well-defined selection criteria and velocity filtering, and is the first CG sample selected by stellar mass. We compared the properties of the 78 v2MCGs with <v> > 3000 km/s with the properties of other CG samples, as well as those (mvCGs) extracted from the semi-analytical model of Guo et al. (2011) run on the high-resolution Millennium-II simulation. In this mvCG sample, 2/3 of the groups are physically dense. The space density of v2MCGs within 6000 km/s is 4 times that of the Hickson sample up to the same distance and with the same criteria used here, but still 40% less than that of mvCGs. The v2MCG constitutes the first group catalogue showing statistically significant signs of wide magnitude gaps (according to Tremaine-Richstone statistics) and centrally located 1st-ranked galaxies, both consistent with the predictions obtained from mvCGs. By virtue of its automatic selection with the popular Hickson criteria, its size, its selection on stellar mass, and its statistical signs of mergers and centrally located brightest galaxies, the v2MCG catalogue appears to be the laboratory of choice to study compact groups of 4 or more galaxies of comparable luminosity.
