The cm and mm Variability of the Blazar Radiant Flux

A. E. Volvach, M. G. Larionov, M. F. Aller, H. D. Aller

Abstract


The radiant flux density variability of the extragalactic source is studied for the 1974-2005 period at the frequencies of 4.8, 8, 14.5, 22 and 36 GHz. The components of about 3 and 30 years of the long-term flux variability can be explained by the nutational and precession motions in a close double black-hole system. The fast flux variability component is not directly connected with rotation of the central black hole.
