Broad-band Modeling of GRB Afterglows
E. Berger, R. Sari, D. A. Frail +1
Observations of GRB afterglows ranging from radio to X-ray frequencies generate large data sets. Careful analysis of these broad-band data can give us insight into the nature of th…
The afterglow, the redshift, and the extreme energetics of the gamma-ray burst 990123
S. R. Kulkarni, S. G. Djorgovski, S. C. Odewahn +26
Afterglow, or long-lived emission, has now been detected from about a dozen well-positioned gamma-ray bursts. Distance determinations made by measuring optical emission lines from…
ASCA Discovery of an X-ray Pulsar in the Error Box of SGR1900+14
K. Hurley, P. Li, C. Kouveliotou +9
We present a 2 - 10 keV ASCA observation of the field around the soft gamma repeater SGR1900+14. One quiescent X-ray source was detected in this observation, and it was in the SGR…
Implications of the radio afterglow from the gamma-ray burst of May 8, 1997
Eli Waxman, Shri R. Kulkarni, Dale A. Frail
Radio observations of the afterglow of the gamma-ray burst GRB970508 provide unique new constraints on afterglow models. The quenching of diffractive scintillation at 4 week delay…
