X-ray reprocessing in Seyfert Galaxies: simultaneous XMM-Newton/BeppoSAX observations
S. Bianchi, G. Matt, I. Balestra +2
We selected a sample of eight bright unobscured (at least at the iron line energy) Seyfert Galaxies observed simultaneously by XMM-Newton and BeppoSAX, taking advantage of the comp…

The HELLAS2XMM survey. V. Near-Infrared observations of X-ray sources with extreme X/O ratios
M. Mignoli, L. Pozzetti, A. Comastri +12
We present the results of deep near-infrared observations of 11 hard X-ray selected sources in the Hellas2XMM survey, with faint optical magnitude (R>24) and high X-ray-to-optical…

X-Ray Evolution of Active Galactic Nuclei and Hierarchical Galaxy Formation
N. Menci, F. Fiore, G. C. Perola +1
We have incorporated the description of the X-ray properties of Active Galactic Nuclei (AGNs) into a semi-analytic model of galaxy formation, adopting physically motivated scaling…
