2006ApJ...642..113G BeppoSAX View of Radio-loud Active Galactic Nuclei Paola Grandi, Giuseppe Malaguti, and Mariateresa Fiocchi Abstract. A systematic analysis of a large sample of radio-loud active galactic nuclei (AGNs) available in the BeppoSAX public archive has been performed. The sample includes 3 narrow-line radio galaxies (NLRGs), 10 broad-line radio galaxies (BLRGs), 6 steep-spectrum radio quasars (SSRQs), and 16 flat-spectrum radio quasars (FSRQs). According to the unified models, these classes correspond to objects with increasing viewing angles. As expected, the presence of a nonthermal beamed component emerges clearly in FSRQs. This class shows in fact a featureless continuum (with the exception of 3C 273) and a significantly flatter average spectral slope. However, traces of a nonthermal Doppler-enhanced radiation are elusive in the other classes. We find that the iron line equivalent widths (EWs) are generally weaker in radio-loud AGNs than in Seyfert 1 galaxies, and we confirm the presence of an X-ray Baldwin effect; that is, a decrease of EW with the 2 -- 10 keV luminosity from Seyfert galaxies to BLRGs and quasars. Since the EW-L_2 -- 10 keV_ anticorrelation is present also in radio-quiet AGNs alone, this effect cannot be ascribed entirely to a strongly beamed jet component. Possible alternative interpretations are explored. Key words: Galaxies: Active, Galaxies: Nuclei, Surveys, X-Rays: Galaxies
