The X-ray spectrum of the luminous quasar RBS 315

With log(lx)47.0 RBS315 is one of the most Xray luminous quasars known.Despite its redshift of z2.69 it is bright enough in Xrays to obtain a high quality spectrum with EPIC. We propose to observe RBS315 for 20 ksec in order to obtain a high SNR Xray spectrum spanning a source frame energy range of0.740 keV. Important spectral features as the 6.4 keV iron fluorescence line,the iron 7.11 keV absorption edge and the Compton reflection hump are redshiftedto favourable energies. We intend to measure the EW, energy, and shape of thefluorescence line and measure the relative contributions of jet emission andnuclear emission to the Xray spectrum. We will also investigate possible intrinsic absorption of the Xray source. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
