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…
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…
How Abundant is Iron in the Core of the Perseus Cluster?
S. Molendi, G. Matt, L. A. Antonelli +5
The analysis of Perseus data collected with the Medium Energy Concentrator Spectrometer (MECS) on board Beppo-SAX shows that the ratio of the flux of the 8 keV line complex (domina…
