Cosmological Uses of Gamma-Ray Bursts
S. G. Djorgovski, S. R. Kulkarni, D. A. Frail +12
Studies of the cosmic gamma-ray bursts (GRBs) and their host galaxies are starting to provide interesting or even unique new insights in observational cosmology. GRBs represent a n…
High-Resolution X-ray and Radio Observations of SGR 1900+14 in the Immediate Aftermath of a Giant Flare
D. W. Fox, D. L. Kaplan, S. R. Kulkarni +1
We present the results of Chandra, RXTE, and VLA observations of SGR 1900+14 in the immediate aftermath of its 2001 April 18 giant flare event. In the X-ray band we find the source…
Brown Dwarfs
Ben R. Oppenheimer, S. R. Kulkarni, John R. Stauffer
After a discussion of the physical processes in brown dwarfs, we present a complete, precise definition of brown dwarfs and of planets inspired by the internal physics of objects b…
The gamma-ray burst of 980425 and its association with the extraordinary radio emission from a most unusual supernova
S. R. Kulkarni, D. A. Frail, M. H. Wieringa +6
Supernova SN 1998bw exploded in the same direction and at the same time as the gamma-ray burst GRB 980425. Here we report radio observations of this type Ic supernova, beginning 4…
