The rotation of Galaxy Clusters
Hrant M. Tovmassian
The method for detection of the galaxy cluster rotation based on the study of distribution of member galaxies with velocities lower and higher of the cluster mean velocity over the…
The Relation between Morphology and Dynamics of Poor Groups of Galaxies
H. Tovmassian, M. Plionis
We investigate the relation between the projected morphology (b/a) and the velocity dispersion (sigma_v) of groups of galaxies using two recently compiled group catalogs, one based…
Richness Dependence of the Recent Evolution of Clusters of Galaxies
M. Plionis, H. Tovmassian, H. Andernach
We revisit the issue of the recent dynamical evolution of clusters of galaxies using a sample of ACO clusters with z<0.14, which has been selected such that it does not contain clu…
On the Formation and Evolution of cD Galaxies
Hrant Tovmassian
The cannibalism mechanism of formation of cD galaxies in clusters of Bautz-Morgan class I is analyzed. Dependences between absolute magnitude of cD galaxies, and of the clusters in…
Properties of Hickson Compact Groups and of the Loose Groups within which they are Embedded
H. Tovmassian, M. Plionis, J. P. Torres-Papaqui
We use the Sloan Digital Sky Survey (SDSS) redshift catalogue to look for galaxies with accordant redshifts in the nearby environment (up to ~2 Mpc) of 15 Hickson Compact Groups (H…
Morphological and Luminosity Content of Poor Galaxy Groups
H. Tovmassian, M. Plionis, H. Andernach
We find that the fraction of early-type galaxies in poor groups (containing from 4 to 10 members) is a weakly increasing function of the number of the group members and is about tw…
