Title of the communication: An accretion disk model for the broad-band high energy spectrum of Cyg X-1
Preliminary abstract (12 lines max.):
The X-ray spectrum of Cyg X-1 and other BHC has often been modelled by thermal Comptonisation and/or Compton reflection. However, observations in different energy bands have given different model parameters. We collect data covering the range 1 keV - 1 MeV and discuss them in the light of a self-consistent accretion disk corona model.
