The dynamical evolution of gravitationally bound groups of galaxies should account for some of the objects seen in the Universe. A numerical simulation of the merging of a compact group shows that the process may result in the formation of bright ellip-tical galaxies. If compact groups are interpreted as transient phases in the dynamical evolution of looser groups, the merger remnants they leave behind exemplify galaxy formation at the present epoch. 
DYNAMICAL EVOLUTION OF COMPACT GROUPS OF GALAXIES
Observations about dynamical aspects of compact groups of galaxies are reviewed, and N-body numerical simulations are applied in order to lend theoretical interpretations to the observational
The formation of compact groups of galaxies
In the compact group of galaxies the galaxies can merge into a few massive ones in a very short time, so they must be formed very recently. On the other hand, according to the theory of structure
Mass Distribution in Compact Groups
New redshift surveys of galaxies in the field of compact groups have discovered a population of faint galaxies which act as satellites orbiting in the potential well of the bright group. Here we
On the Verge of Coalescence: a Dusty Group of Galaxies
We found a new, very compact group of galaxies characterized by a median projected separation between galaxies of 5.2/h kpc and a very low velocity dispersion. All the observed member galaxies show
Compact Groups of Galaxies
▪ Abstract Compact groups of galaxies have posed a number of challenging questions. Intensive observational and theoretical studies are now providing answers to many of these and, at the same time,
Optical Colors of Early-Type Galaxies in Compact Groups
Compact groups of galaxies with high spatial densities and low velocity dispersions are very unstable to merging. The mergers of spiral galaxies shoud be common in these environments, and if
The chemical evolution of galaxies
The chemical evolution of galaxies is discussed starting with the simple box model. It is shown that this model with the additional assumption of metal-rich outflow provides a first useful insight
Merger History of Central Galaxies in Semi-analytic Models of Galaxy Formation
We investigate the dynamical evolution of galaxies in groups with different formation epochs. Galaxy groups have been selected to be in different dynamical states, namely dynamically old and
On the Large‐Scale Structure of Hickson Compact Groups of Galaxies
Abstract: We present a study on the integral two‐point correlation functions of Hickson compact groups of galaxies. The results show no evidence that these objects form large‐scale structures beyond
The Onset of a Three-Galaxy Merger in the Compact Group of Galaxies HCG 95?
In this Letter we report new evidence for a close three-galaxy interaction in the compact group of galaxies HCG 95. Deep optical imaging in the Johnson UBVRI bands and in narrowband Hα have shown

Galaxy counts are reported within 1 deg of the 100 dense groups cataloged by Hickson (1982). The results suggest that a much smaller fraction of the groups can be explained as chance alignments than
