CYGNUS-X-1 Revisited
Abstract
We review the X- and gamma-ray observations of Cygnus X-1 and their theoretical interpretations, with emphasis on new developments since the mid-1970's. The overall data base at present is most consistent with the inverse Compton model by hot thermal electrons of T e ∼ 109 K, for the hard X-ray luminosity (10 200 keV). However, the origin of the soft X-rays (≤ 10 keV) in high states and gamma rays (> 200 keV) remain unsettled.
