Catálogo de Grupos Compactos del 2MASS
Abstract
We present a catalog of Compact Groups automatically extracted from the 2MASS extended source catalog (Sktrutskie et al. 2006). Following the cri- teria defined by Hickson (1982), we find 329 Compact Groups. After a vi- sual inspection, we find out that only 295 groups constitute our final catalog, due to some galaxy miss-identifications in the parent catalog. Finally, we found 17% previously known Compact Groups while the remaining (83%) represents a brand new sample. From these Compact Groups, 172 have all their members with redshifts available in the literature, however only 97 of these groups (56%) have four or more accordant galaxies. This is the largest velocity filtered sample available at present and constitutes the baseline to our statistical studies of Compact Groups.
