| Abstract: | It is more appropriate to study the dynamics and evolution of compact groups using a sample of isolated compact groups in
the nearby vicinity of which there are no accordant redshift galaxies. To look for isolated compact groups we inspected the
environment of 78 Shakhbazian compact groups, with known redshifts. We found that 26 of nearby groups with V < 40000 km s−1 are isolated compact groups in the vicinity of which up to a projected distance of 1 Mpc there are no accordant redshift
galaxies. For four of them, the redshift of only two members are known, so their being groups is not certain. In the vicinities
of eleven distant groups (V > 40000 km s−1) no accordant redshift galaxies are detected as well. The reason for this may be the faintness of galaxies there. These groups
may possibly be isolated. |
