Gamma-ray bursts and black holes. Interpretation of the observational data

Abstract

The paper relies upon the (Kuznetsov 2000), where the cosmic gamma - ray bursts (GRBs) in clusters are shown to have an apparent shift relative to the position of the source. Hence the main conclusion follows: only cluster of GRBs ensures correct localization of the source whereas determining the direction of arrival of a single GRB practically carries no information about the position of its source. Generation of repeated GRBs in the activity phase of the source, which amounts to 3-4 months and with the period of repetition of activity equal to 4 years are most general properties of clusters. These properties precisely correspond to the characteristics of manifestation of activity of X-ray NOVAE (BHXN), thus pointing that the source of GRB clusters considered is a black hole (BH) in the XN. The direct identification of the GRB source with the BHXN GRO J0422+32 presented here this confirms. The investigated properties of GRB clusters permit a final solution of 2 main problems of astrophysics: search for black holes and origin of cosmic GRBs.
