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…
Prompt Optical Emission from Gamma-ray Bursts
Robert Kehoe, Carl Akerlof, Richard Balsano +19
The Robotic Optical Transient Search Experiment (ROTSE) seeks to measure contemporaneous and early afterglow optical emission from gamma-ray bursts (GRBs). The ROTSE-I telescope ar…
The X-ray spectra of VW Hydri during the outburst cycle
H. W. Hartmann, P. J. Wheatley, J. Heise +2
We report six BeppoSAX X-ray observations of VW Hydri during and after the outburst of Sep 23 1998. The outburst flux is lower than the quiescent flux in the entire observed energy…
Discovery of type-I X-ray bursts from GRS 1741.9-2853
M. Cocchi, A. Bazzano, L. Natalucci +4
For the first time X-ray bursts have been detected from a sky position consistent with the one of GRS 1741.9-2853, a GRANAT transient source located only ~10' from the Galactic Cen…
Spectral Energy Distributions and Light Curves of GRB 990123 and its Afterglow
T. J. Galama, M. S. Briggs, R. A. M. J. Wijers +38
Gamma-ray bursts (GRBs) are thought to result from the interaction of an extremely relativistic outflow interacting with a small amount of material surrounding the site of the expl…
A new X-ray outburst in the globular cluster NGC 6440: SAX J1748.9-2021
J. J. M. in 't Zand, F. Verbunt, T. E. Strohmayer +8
For the second time in 27 years a bright transient X-ray source has been detected coincident with the globular cluster NGC 6440. It was found to be active in August, 1998, with the…
