VLT spectroscopy of GRB 990510 and GRB 990712; probing the faint and bright end of the GRB host galaxy population
P. M. Vreeswijk, A. Fruchter, L. Kaper +15
We present time-resolved optical spectroscopy of the afterglows of the gamma-ray bursts GRB 990510 and GRB 990712. Through the identification of several absorption lines in the fir…
Precise Interplanetary Network Localization of the Bursting Pulsar GRO J1744-28
K. Hurley, C. Kouveliotou, T. Cline +8
We analyze 426 observations of the bursting pulsar GRO J1744-28 by Ulysses and BATSE. Triangulating each burst, and statistically combining the triangulation annuli, we obtain a 3…
Observations of a possible new soft gamma repeater, SGR1801-23
T. Cline, D. D. Frederiks, S. Golenetskii +4
We report on two observations of a soft bursting source in 1997 June, whose time histories and energy spectra are consistent with those of the soft gamma repeaters. The source can…
Where is SGR1806-20?
K. Hurley, C. Kouveliotou, T. Cline +4
We apply a statistical method to derive very precise locations for soft gamma repeaters using data from the interplanetary network. We demonstrate the validity of the method by der…
The X-ray, Optical and Infrared Counterpart to GRB 980703
P. M. Vreeswijk, T. J. Galama, A. Owens +36
We report on X-ray, optical and infrared follow-up observations of GRB 980703. We detect a previously unknown X-ray source in the GRB error box; assuming a power law decline we fin…
A ROSAT Deep Survey of Four Small Gamma-Ray Burst Error Boxes
K. Hurley, P. Li, M. Boer +11
We have used the ROSAT High Resolution Imager to search for quiescent X-ray counterparts to four gamma-ray bursts which were localized to small (< 10 sq. arcmin.) error boxes with…
