Radiative Processes in Microquasars
摘要
Recent advances in the X-ray and soft gamma-ray observations of accreting black holes and microquasars, in particular, are reviewed. The radiative processes responsible for the emission are discussed briefly. The hybrid thermal/nonthermal Comptonization model is shown to describe well the observed broad-band spectra. We also comments on alternative phenomenological and physical models that are used to describe the X/gamma-ray spectra of accreting black holes. Among those are the "standard" model (i.e. disk-blackbody plus a power-law), pexrav, bulk motion Comptonization, and synchrotron emission from the jet.
