The nuclear environment of radio-loud broad line AGN

We propose to obtain high signaltonoise RGS spectra of the Broad Line RadioGalaxies (BLRGs) 3C120 and 3C390.3 in order to investigate the physicalproperties, the geometry and dynamics of their nuclear environments, whichare likely to be dominated by the presence of relativistic jets. We willcompare them with those of Seyfert galaxies, which are thought to be theradioquiet analogues of BLRGs, and for some of which good quality RGS spectrahave already been obtained. The associated EPIC spectra will provide data onthe strengths and profiles of the Fe K _\\alpha emission lines, and will testthe hypothesis that such line may originate in the jet rather than in theaccretion disk. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
