INTEGRAL monitoring of the Black Hole candidate 1E 1740.7-2942
M. Del Santo, A. Bazzano, D. M. Smith +24
The brightest persistent Galactic black hole candidate close to the Galactic Centre, 1E 1740.7-2942, has long been observed with INTEGRAL. In this paper, we report on the long-term…
A Sample of Radius-Expansion Bursters Observed by the BeppoSAX-WFCs
Massimo Cocchi, A. Bazzano, L. Natalucci +5
Since 1996 a monitoring campaign of the Galactic Bulge region has been performed by the BeppoSAX Wide Field Cameras in the 2-28 keV band. This allowed accurate and unbiased studies…
Gamma-Ray Imaging with the Coded Mask IBIS Telescope
A. Goldwurm, P. Goldoni, A. Gros +6
The IBIS telescope onboard INTEGRAL, the ESA gamma-ray space mission to be launched in 2002, is a soft gamma-ray (20 keV - 10 MeV) device based on a coded aperture imaging system.…
Turmoil on the accretion disk of GRO J1655-40
E. Kuulkers, J. J. M. in 't Zand, R. Cornelisse +7
During the 1996/1997 outburst of the X-ray transient GRO J1655-40 the Wide Field Cameras onboard BeppoSAX observed the system with nearly continuous coverage during some stages of…
BeppoSAX observations of the nearby low-mass X-ray binary and fast transient SAX J1819.3-2525
J. J. M. in 't Zand, E. Kuulkers, A. Bazzano +7
SAX J1819.3-2525 is a nearby X-ray transient which exhibited a fast and large X-ray outburst on Sep. 15, 1999 (Smith et al. 1999). The Wide Field Cameras and the Narrow Field Instr…
The orbital period of the recurrent X-ray transient in Terzan 6
J. J. M. in 't Zand, A. Bazzano, M Cocchi +11
Four or five new outbursts were detected of the bright X-ray transient GRS 1747-312 in the globular cluster Terzan 6 between 1996 and 1999, through monitoring campaigns with the Wi…
