The X-ray properties of the PG QSO sample observed with XMM-Newton
Elena Jimenez-Bailon, Enrico Piconcelli, Matteo Guainazzi +1
We present preliminary results of a systematic analysis of the XMM-Newton spectra of nearby optically-bright QSOs. The objects have been optically selected from the Bright Quasar S…
Relativistic spectral features from X-ray illuminated spots and the measure of the black hole mass in AGN
M. Dovciak, S. Bianchi, M. Guainazzi +2
Narrow spectral features in the 5--6 keV range were recently discovered in the X-ray spectra of a few active galactic nuclei. We discuss the possibility that these features are due…
The starburst-AGN of NGC1808 observed with XMM-Newton
E. Jimenez-Bailon, M. Santos-Lleo, M. Dahlem +3
NGC1808 is a nearby spiral galaxy that harbours an active central region with an extent of 20 arcsec (i.e. 1 kpc). Previous X-ray and optical/NIR observations have provided convinc…
The Compton-thick AGN in the GPS radio source OQ+208
M. Guainazzi, C. Stanghellini, P. Grandi
We report in this paper the ASCA discovery of the first radio-loud Active Galactic Nucleus (AGN) covered by a Compton-thick X-ray absorber, in the GigaHertz Peaked Spectrum (GPS) r…
BeppoSAX observations of Mrk 509 and MCG+8-11-11
G. C. Perola, G. Matt, F. Fiore +7
BeppoSAX observations of the Seyfert galaxies Mrk 509 and MCG+8-11-11 are presented. Earlier evidence of a soft excess in Mrk 509 is confirmed. This excess is found to be better re…
BeppoSAX spectroscopy of the globular cluster X-ray source X1746-371 (NGC6441)
A. N. Parmar, T. Oosterbroek, M. Guainazzi +3
During a BeppoSAX observation of the X-ray source X1746-371 located in the globular cluster NGC6441 a type I X-ray burst, parts of 4 intensity dips, and energy dependent flaring we…
