BeppoSAX observations of Narrow-Line Seyfert 1 galaxies:I. Ton S 180
A. Comastri, F. Fiore, M. Guainazzi +10
We report on the first spectrum up to 10 keV of the bright narrow-line Seyfert 1 galaxy Ton S 180, obtained with the imaging instruments onboard BeppoSAX. This is the first observe…
A BeppoSAX LECS observation of the super-soft source CAL83
A. N. Parmar, P. Kahabka, H. W. Hartmann +1
We report on a BeppoSAX Low-Energy Concentrator Spectrometer (LECS) observation of the super-soft source (SSS) CAL83. The X-ray emission in SSS is believed to arise from nuclear bu…
Evidence for a late-time outburst of the X-ray afterglow of GB970508 from BeppoSAX
L. Piro, L. Amati, L. A. Antonelli +15
The gamma-ray burst GB970508 was observed simultaneously by the Gamma Ray Burst Monitor (GRBM) and one of the X-ray Wide Field Cameras (WFC) aboard BeppoSAX. The latter provided a…
The complex X-ray spectrum of the low-mass X-ray binary 4U 1626-67
A. Owens, T. Oosterbroek, A. N. Parmar
We report on observations of the X-ray pulsar 4U 1626-67 by the LECS instrument on-board Bepposax. We confirm the recent ASCA discovery of excess emission near 1 keV (Angelini et a…
