BeppoSAX uncovers a type-2 QSO in the hyperluminous infrared galaxy IRAS 09104+4109
A. Franceschini, L. Bassani, L. Cappi +4
We studied with BeppoSAX the infrared luminous galaxy IRAS 09104+4109 over a very wide X-ray band from 0.1 to 80 keV. Our observations indicate the dominance of a thermal component…
BeppoSAX observations of Mkn 3: Piercing through the torus of a Seyfert 2 galaxy
M. Cappi, L. Bassani, A. Comastri +15
A new BeppoSAX broad-band (0.6-150 keV) spectrum of the Seyfert 2 galaxy Mkn 3 is presented. The spectrum provides a direct measurement of a large, neutral column of gas with Nh~10…
One more surprise from the Circinus Galaxy: BeppoSAX discovery of a transmission component in hard X-rays
G. Matt, M. Guainazzi, R. Maiolino +11
The Circinus Galaxy has been observed, for the first time above 10 keV, by BeppoSAX. An excess emission above the extrapolation of the best fit 0.1--10 keV spectrum is apparent in…
X-ray detections of weak Seyfert2's with BeppoSAX
M. Salvati, L. Bassani, R. Della Ceca +3
We report the detection in the X rays of two weak Seyfert2's (NGC3393 and NGC4941) with the Italian-Dutch satellite BeppoSAX. These are among the first sources observed in a sample…
