A BeppoSAX study of the pulsating transient X0115+63: the first X-ray spectrum with four cyclotron harmonic features
A. Santangeo, A. Segreto, S. Giarrusso +9
The recurrent hard pulsating X-ray transient §was observed with \B on March 19, when the source was at a 2--10 keV flux level of 310~mCrab. We report on the high energy spect…

The Vela X-1 pulse-averaged spectrum as observed by BeppoSAX
M. Orlandini, D. Dal Fiume, F. Frontera +7
We report on the 20 ksec observation of Vela X-1 performed by BeppoSAX on 1996 July 14 during its Science Verification Phase. We observed the source in two intensity states, charac…

A BeppoSAX observation of 3C273: broadband spectrum and detection of a low-energy absorption feature
P. Grandi, M. Guainazzi, T. Mineo +12
We report the results of a 3C273 observation performed during the Science Verification Phase (SVP) of the BeppoSax satellite. The broad-band spectrum is well represented by a power…
