Abstract

According to the long-term monitoring on 3 radio band frequencies (4.8, 8 and 14.5 GHz) obtained at the Observatory of the University of Michigan, studied extragalactic radio sources 3C 120, CTA 102, DA 55, and OJ 287. According to apply Fourier methods and wavelet analysis, which revealed a change of harmonic signal components over time. Identified long-period (trend) and short-period components for each source at all frequencies studied. According to the VLBI studied the movement of bright component in the jet.

Keywords: extragalactic radio sources; physical properties
