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…
NGC3147: a "true" Seyfert 2 without the broad-line region
S. Bianchi, A. Corral, F. Panessa +5
We report on simultaneous optical and X-ray observations of the Seyfert galaxy, NGC3147. The XMM-Newton spectrum shows that the source is unabsorbed in the X-rays ($N_H<5\times10^{…
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…
XMM-Newton observation of the deep minimum state of PG 2112+059: A spectrum dominated by reflection from the accretion disk?
N. Schartel, P. M. Rodriguez-Pascual, M. Santos-Lleo +5
We analyse a 75ks XMM-Newton observation of PG 2112+059 performed in November 2005 and compare it with a 15ks XMM-Newton observation taken in May 2003. PG 2112+059 was found in a d…
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…
