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…
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…
The absorption properties of gamma-ray burst afterglows measured by BeppoSAX
Alan Owens, M. Guainazzi, T. Oosterbroek +14
We present an analysis of the X-ray absorption properties of 6 gamma-ray burst (GRB) afterglows measured with BeppoSAX. Between 8 hrs and 20 hrs after the initial GRB trigger, indi…
BeppoSax Spectral Survey of soft X-ray selected BL Lacs
A. Wolter, A. Comastri, G. Ghisellini +10
We present X-ray spectra obtained with BeppoSAX (Satellite per Astronomia X) of 10 BL Lac objects, selected from the Einstein Medium Sensitivity and Slew Surveys. We find that in a…
The X-ray emission of the polar BL Hydri
G. Matt, R. Barcaroli, T. Belloni +8
We report on the analysis of the ASCA and BeppoSAX X-ray observations of the polar system BL Hyi. Emission from both poles is apparent in both observations; the emission from the s…
