Possible Electromagnetic Manifestations of Merging Black Holes

Bisikalo, D. V.; Zhilkin, A. G.; Kurbatov, E. P.

The scenario of a merger of two black holes surrounded by an accretion disk is considered. As a result of the emission of gravitational waves, the mass of the central object decreases, and the accretion disk is perturbed. Computational results show that the main consequence of this perturbation is the formation of a shock propagating from the cent…

2070 unique, homogeneous photometric and polarization observations of the microquasar in a binary system with a black hole V404 Cyg/GS2023+338 obtained in 2015 with the MASTER global network of robotic telescopes (16 robotic telescopes located at eight points on the Earth in Russia, Spain, South Africa, and Argentina) are presented. MASTER was the…
