Resonant Absorption in the AGN spectra emerging from photoionized gas: differences between steep and flat ionizing continua
Fabrizio Nicastro, Fabrizio Fiore, Giorgio Matt
We present photoionization models accounting for both photoelectric and resonant absorption. Resonance absorption lines from C, O, Ne, Mg, Si S and Fe between 0.1 and 10 keV are tr…
The BeppoSAX High Energy Large Area Survey (HELLAS)
F. Fiore, P. Giommi, F. La Franca +9
We have surveyed about 50 deg-2 of sky in the largely unexplored 5-10 keV band using the BeppoSAX MECS instrument, finding 180 sources. After correction for the non uniform sky cov…
X/gamma-ray spectra of Seyferts and BeppoSAX observations
Giorgio Matt
BeppoSAX results on Seyfert galaxies are reviewed and discussed.
Studying circumnuclear matter in AGN with X-ray spectroscopy
Giorgio Matt
I discuss the advances in our understanding of the physics and morphology of the innermost regions of AGNs which will be possible thanks to the XMM unprecedented sensitivity and it…
Reprocessing and Variable Cold Absorption in the Broad-Line Radio Galaxy 3C390.3
P. Grandi, M. Guainazzi, F. Haardt +5
A BeppoSAX observation of the BLRG 3C390.3 is reported. For the first time, both the 6.4 keV iron line and a strong reflection hump, produced by the illumination of the primary X-r…
Beppo-Sax Observation of the Coma cluster
R. Fusco-Femiano, D. Dal Fiume, L. Feretti +3
We present first results of the BeppoSAX observation of the Coma Cluster. Thanks to the unprecedented sensitivity of the PDS instrument, the source has been detected up to ~80 keV.…
