Multi-frequency Radio Photometry of the Microquasars with the RATAN-600 Radio Telescope |
The 1-30 GHz light curves of the microquasars GRS1915+105, Cyg X-3, and SS433 were measured in the intensive daily monitoring programs with the RATAN-600 (SAO RAS) radio telescope during 2002-2009. A lot of powerful flaring events were detected, being alerts of the VLBI or e-VLBI mapping. We detected clear correlations between radio emission (RATAN), soft (ASM XTE) and hard (ASM Swift/BAT) X-ray emission for Cyg X-3 and GRS 1915+105. The repeatedly similar pre-flaring evolution of the radio and X-ray emission of Cyg X-3 allow us to predict the strong flares (>3 Jy) as in the case of the flare in December 2008. We used it in the high-energy emission (MAGIC, EGILE) search of the X-ray binary. The super-critical black hole accretor SS433 was mapping with the European e-VLBI during its unusual radio activity in November 2008. |
