Modes of mass-loss in Microquasars


Black holes in our Galaxy, such as those in the microquasars SS433 and Cygnus X-3, demonstrate dynamic behaviour in accretion and dramatic mass outflows. We observe winds and relativistic plasma jets to emerge from these objects which resemble the the winds and relativistic plasma jets to emerge from these objects whick resemble the modes of mas-loss in the supermassive black holes of powerful quasars in the distant universe. Time-resolved observations of the accretion and subsequent mass-loss from microquasars offers great rewards in therms of information about the nature of these remarkable phenomena in the Universe. I will describe how combined multi-wavelength strategies across the electromagnetic spectum continu to yield new discoveries and discuss how time-resolved observations have let to the discovery of a further mode of mass-loss in SS433 via a circumbinary disc. I shall present the exquisitely detailed behaviour of these modes of mas-loss before, during and after a major flare event in this object, with reference to comparable behavior seen in similar objects.
