Observations of the Galactic Center Region with Beppo-Sax
L. Sidoli, S. Mereghetti
We are performing a survey of the Galactic Center region with the BeppoSAX satellite. Several known point sources are visible (including one at the position of SgrA*), as well as n…
Fast X-ray Variability of PKS 2155-304: A Cross Correlation Analysis
A. Treves, Y. H. Zhang, A. Celotti +7
PKS 2155-304 is one of the prototypes of BL Lac objects. Its spectral energy distribution is known from the radio to the TeV band and has two peaks, one in the soft X-rays and the…
BeppoSAX Observations of the BL Lac Object Mkn 501 in an Intermediate State
Elena Pian, Eliana Palazzi, Lucio Chiappetti +8
The BL Lac object Mkn 501 was observed with the BeppoSAX satellite at three epochs in April-May 1998, simultaneously with the Whipple and HEGRA Cherenkov telescopes. The X-ray spec…
BeppoSAX Observations of PKS 2155-304 during an active Gamma-ray State
L. Maraschi, L. Chiappetti, F. Tavecchio +8
PKS 2155-304 was observed with BeppoSAX in November 1997 for 64 ksec (total elapsed time 33.5 hours) and, for the first time, simultaneously in gamma-rays with EGRET on board the C…
BeppoSAX observations of a new X-ray burster in the Galactic Center region, possibly coincident with a recurrent transient
L. Sidoli, S. Mereghetti, G. L. Israel +3
We report BeppoSAX NFI observations of the X-ray source SAX~J1747.0--2853 recently discovered in the region of the Galactic Center. The presence of type I X-ray bursts indicates th…
BeppoSAX observations of the long period polar system V1309 Ori
D. de Martino, R. Barcaroli, G. Matt +8
We present BeppoSAX observations of the peculiar long period polar system V1309 Ori (RXJ0515.6+0105). The source was detected simultaneously at soft and, for the first time, at har…
