The broad iron lines in X-ray weak quasars

Recent XMMNewton and Chandra observations show strong indications that Xrayweak quasar.s spectra harbor a relativistically broaden iron line. Three observations of Xray weak quasars show unique absorbing material with physical conditions, which are not comparable with the absorbers described for AGNs so far:The absorbers in Xray weak quasars have much higher column density and ionization parameter. This can be understood if our line of sight to the nucleus grazesthe upper tip of the torus. We propose observations of two Xray weak quasarsfor which relativistic iron lines have been detected to determine the linephysical parameters. We want to measure the disk inclination angle and to checkif it is aligned with the viewing angle suggested by the absorption features. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
