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…
Quasi-simultaneous observations of 3C 273 by BeppoSAX and ASCA
Astrid Orr, T. Yaqoob, A. N. Parmar +3
We report the results of quasi-simultaneous observations of the bright quasar 3C 273 using the BeppoSAX Low-Energy Concentrator Spectrometer (LECS) and the ASCA Solid-State Imaging…
High resolution imaging of the X-ray afterglow of GRB970228 with ROSAT
F. Frontera, J. Greiner, L. A. Antonelli +6
We report results of a ROSAT High-Resolution Imager (HRI) observation of the X-ray error box given by the BeppoSAX Wide Field Camera for the gamma-ray burst that occurred on 1997 F…
