Head Volvach Alexandr Evgenievich, Registration Date 14-12-2009 Organization Scientific-research institute "Crimean astrophysical observatory" popup.description2 On the basis of long-term monitoring of 7 active galactic nuclei observed at the Crimean Astrophysical Observatory at 22.2 and 36.8 GHz carried out an analysis of periodic components of flux variability. The brightest representative’s active galaxies, observed as nonstationary sources in broad range of the wave lengths, are a binary system of supermassive black holes, residing on the close to coalescence stage of the evolutions. The parameters for the supposed binary black-hole system are determined: the masses of the central object and its companion, the radius of the companion’s orbit and the coalescence time.
