Theoretical aspects of microquasars

Microquasars (black hole X-ray binaries with relativistic jets) are first found by means of multiwavelengths observations with ground-based telescopes. Microquasars mimic, on a much smaller scale, many of their phenomena seen in quasars. The study about microquasars opens the door for better understanding of the relativistic jets elsewhere in the Universe, and may serve to determine the distance of the jet sources; the connection between the flow instabilities and the ejection of relativistic clouds (formation of jet); the fundamental plane of black hole activity and the black hole’s spin.
