Structure of the Accretion Flows in Broad-Line Radio Galaxies

We propose to observe four of the Xray brightest broadline radiogalaxies in order to investigate the differneces between the profilesof the Fe K lines of radioloud and radio quiet AGNs. We will obtainspectra with very high signaltonoise ratio with EPIC so that we canfit the line profiles with disk models and determine the range of radii in the disk where the lines originate. This constitutes a testof scenarios for the difference between radioloud and radioquietAGNs since such scenrios predict different disk structures and byextension different line profiles. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
