BeppoSAX observations of the quasar Markarian 205.

Abstract (from CDS):

We present the first BeppoSAX observation (0.1 to 220keV) of the quasar Mrk 205. We have searched for the unusual Fe line profile observed in the XMM-Newton spectrum which has been widely discussed in the recent literature. We find no evidence for a broad, ionized Fe line component in our data. We detect for the first time a Compton hump in this object. When this component is included in the fit, the line strength diminishes, in agreement with a recent re-analysis of the XMM-Newton data, but with better constraints on the reflection component thanks to the PDS instrument (15-220keV). We interpret this fact as another indication for illumination of distant, cold material rather than reprocessing in the highly ionized inner part of an accretion disk. We cannot constrain the presence of a high energy cutoff but we confirm the existence of a variable soft excess (one year time scale).
