BeppoSAX discovery of a new Seyfert 2 galaxy: 1SAXJ2234.8-2541
A. Malizia, L. Bassani, I. Negueruela
In the present work we report the BeppoSAX serendipitous discovery of the type 2 AGN 1SAXJ2234.8-2541 in the MECS field of view when pointing at the Seyfert 2 galaxy NGC7314. The s…
Hard X-ray emission from the galaxy cluster A2256
R. Fusco-Femiano, D. Dal Fiume, S. De Grandi +6
After the positive detection by BeppoSAX of hard X-ray radiation up to ~80 keV in the Coma cluster spectrum, we present evidence for nonthermal emission from A2256 in excess of the…
A Long Observation of NGC 5548 by BeppoSAX: the High Energy Cut-off, Intrinsic Spectral Variability and a Truly Warm Absorber
F. Nicastro, L. Piro, A. De Rosa +11
NGC 5548 was observed by BeppoSAX in a single long (8 day) observation from 0.2 to 200 keV. We find (1) the spectral variation of the source is produced by a change of the intrinsi…
