Abstract
We present the results of the detailed photometric and spectroscopic study of Shakhbazian compact galaxy groups ShCG 104, ShCG 120, ShCG 223 and ShCG 245. The redshifts of member galaxies, the results of photometry in R band, the surface-brightness profiles, the curves of isophotal twisting and Fourier parameter a_4 are presented. We determined the mass, the luminosity, the mass-to-luminosity ratio, the radial velocity dispersion and the crossing time of groups. Also the morphological types of member galaxies are determined. It is shown that some galaxies in groups are in the process of interaction.Similar Articles
