On Massive Black Holes in the Centers of Globular Clusters. I

In this paper, a sample of globular clusters (GCs), for which the masses of black holes in their centers are known from observations, has been created. The dependence of the main characteristics of GCs on the mass of black holes has been studied. Based on observational data on the surface density of GCs, the degree of concentration of stars to their center has been determined. The obtained degree of concentration has been used as an indicator of the presence of black holes.
