The recent history of the X-ray absorber in NGC3516
M. Guainazzi, W. Marshall, A. N. Parmar
We present two BeppoSAX observations of the bright Seyfert 1 galaxy NGC3516, performed four months apart (late 1996/early 1997). The earlier spectrum is considerably weaker and har…
Unusual quiescent X-ray activity from XTE J0421+560 (CI Cam)
A. N. Parmar, T. Belloni, M. Orlandini +3
We report on BeppoSAX observations of the X-ray transient XTE J0421+560 in quiescence 156, 541, and ~690 days after the maximum of the 1998 April outburst. In the first observation…
X-ray observations during a Her X-1 anomalous low-state
A. N. Parmar, T. Oosterbroek, D. Dal Fiume +4
Results of a 1999 July 8-10 BeppoSAX observation during an anomalous low-state of Her X-1 are presented. The standard on-state power-law and blackbody continuum model is excluded a…
Constraining the spectral parameters of RXJ0925.7-4758 with the BeppoSAX LECS
H. W. Hartmann, J. Heise, P. Kahabka +2
The Super Soft Source RX J0925.7--4758 was observed by BeppoSAX LECS and MECS on January 25--26 1997. The source was clearly detected by the LECS but only marginally detected by th…
Evidence for ionized reprocessing in the X-ray spectrum of the Seyfert 1 Galaxy 1E1615+061
M. Guainazzi, L. Piro, M. Capalbi +3
The Seyfert 1 galaxy 1E1615+061 was observed to display a very steep and intense soft X-ray spectrum during a HEAO-1 A2 observation in the 1978. Such an exceptionally soft X-ray st…
BeppoSAX follow-up search for the X-ray afterglow of GRB970111
M. Feroci, L. A. Antonelli, M. Guainazzi +17
The BeppoSAX satellite has recently opened a new way towards the solution of the long standing gamma-ray bursts' (GRBs) enigma, providing accurate coordinates few hours after the e…
