Heavy absorption and soft X-ray emission lines in the XMM-Newton spectrum of the Type 2 radio-loud quasar 3C 234
E. Piconcelli, S. Bianchi, G. Miniutti +4
We report results on a 40 ks XMM-Newton observation of the Type 2 quasar 3C 234. Optical spectropolarimetric data have demonstrated the presence of a hidden broad-line region in th…
X-ray properties of a sample of polar-scattered Seyfert galaxies
E. Jimenez-Bailon, M. Guainazzi, G. Matt +5
We present the results on an XMM-Newton systematic analysis of a sample of nine Seyfert 1 galaxies. When observed in polarised light, the spectra of the selected sources are simila…
Heavily obscured AGN with BeppoSAX, INTEGRAL, SWIFT, XMM and Chandra: prospects for Simbol-X
R. Della Ceca, P. Severgnini, A. Caccianiga +6
According to the latest versions of synthesis modeling of the Cosmic X-ray Background, Compton Thick AGN should represent ~50% of the total absorbed AGN population. However, despit…
The XMM-Newton view of IRAS 09104+4109: evidence for a changing-look Type 2 quasar?
E. Piconcelli, F. Fiore, F. Nicastro +4
We analyzed the spectroscopic data from the PN and the MOS cameras in the 0.4-10 keV band. We also used an archival BeppoSAX 1-50 keV observation of IRAS 09104+4109 to investigate…
XMM-Newton view of galaxy pairs: activation of quiescent black holes?
E. Jimenez-Bailon, N. Loiseau, M. Guainazzi +4
We report on XMM-Newton observations of three nearby galaxy pairs, AM0707-273, AM1211-465, and AM2040-674. All six galaxies were previously classified as HII galaxies based on opti…
XMM-Newton broad-band observations of NGC 7582: Nh variations and fading out of the active nucleus
E. Piconcelli, S. Bianchi, M. Guainazzi +2
We present results from two XMM-Newton observations of the bright classical Seyfert 2 galaxy NGC 7582 taken four years apart (2001 May and 2005 April). We present the analysis of t…
