Abstract

The data of multi-frequency observations of the blazar AO 0235+164 in radio waves ranges are analyzed. Evidence of the duality of a system consisting of two supermassive black holes, which are at the stage of evolution close to fusion, is found. With the help of harmonic analysis, possible values of the orbital and precession periods in the system are established, similar to those obtained for other bright representatives of AGN. The time shifts of flare phenomena occurring in different frequency ranges correspond to the hypothesis of a plasma cloud moving along the jet, which is bleached sequentially at lower and lower frequencies, what indicates rather the internal nature of variability of the flux density in AO 0235+164. The physical and dynamic characteristics of AGN AO 0235+164  suggest that this close system consists of  supermassive black holes with similar masses of the order of 1010 M.
