"Orphan" afterglows in the Universal Structured Jet Model for gamma-ray bursts

open access: yes, 2008
The paucity of reliable achromatic breaks in Gamma-Ray Burst afterglow light curves motivates independent measurements of the jet aperture. Serendipitous searches of afterglows, especially at radio wavelengths, have long been the classic alternative ...

Are HI Supershells the Remnants of Gamma-Ray Bursts?

open access: yes, 1998
Gamma-Ray Bursts (GRBs) are thought to originate at cosmological distances from the most powerful explosions in the Universe. If GRBs are not beamed then the distribution of their number as a function of Gamma-ray flux implies that they occur once per (0.

Identifying the Environment and Redshift of GRB Afterglows from the Time-Dependence of Their Absorption Spectra [PDF]

open access: yes, 1997
The discovery of Gamma-Ray Burst (GRB) afterglows revealed a new class of variable sources at optical and radio wavelengths. At present, the environment and precise redshift of the detected afterglows are still unknown.
