BeppoSAXView of Radio‐loud Active Galactic Nuclei

A systematic analysis of a large sample of radio-loud Active Galactic Nucleiavailable in the BeppoSAX public archive has been performed. The sampleincludes 3 Narrow Line Radio Galaxies (NLRG), 10 Broad Line Radio Galaxies(BLRG), 6 Steep Spectrum Radio Quasars (SSRQ), and 16 Flat Spectrum RadioQuasars (FSRQ). According to the unified models, these classes correspond toobjects with increasing viewing angles. As expected, the presence of anon-thermal beamed component emerges clearly in FSRQ. This class shows in facta featureless continuum (with the exception of 3C273), and a significantlyflatter average spectral slope. On the contrary, traces of a non-thermalDoppler enhanced radiation are elusive in the other classes. We find that theiron line equivalent widths (EW) are generally weaker in radio- loud AGN thanin Seyfert 1 galaxies, and confirm the presence of an X-ray Baldwin effect,i.e. a decrease of EW with the 2--10 keV luminosity (L) from Seyferts to BLRGand quasars. Since the EW--L anti-correlation is present also in radio-quietAGN alone, this effect cannot be ascribed entirely to a strongly beamed jetcomponent. Possible alternative interpretations are explored.Comment: ApJ accepted, 33 pages, 6 figure
