Scientific paper

Several hundred black hole (BH) candidates have been discovered up to now. Statistical investigations of relativistic objects have been carried out. Neutron stars (NS) and stellar-mass BHs presumably have a bimodal distribution over their masses in contrast with distribution of CO-core masses of massive stars being progenitors of relativistic objects. Masses of supermassive BHs in galactic nuclei correlate with the luminosity of the galactic bulge as well as with the bulge velocity dispersion. Correlation between rotational velocity of a galaxy and the mass of its central supermassive BH is investigated by direct comparison of an observed rotational velocity of the galaxy with the dynamically determined mass of the central supermassive BH.
