SEARCH FOR BINARY GALAXIES IN MULTIPLE SYSTEMS

Binary galaxies, multiple galaxies, statistical analysis.

Authors

In this paper, a list of 89 multiple galaxies was compiled and a statistical analysis was performed based on their morphological types, distances between them, and radial velocity differences. An empirical relationship was determined between the masses of the galaxies and the black holes at their centers. Physical and optical binary galaxies were distinguished based on three criteria. According to the analysis, 29% of the galaxies in this list are physical pairs, 71% are optical pairs, and the majority of pairs are spiral galaxies.
