Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB 030329
J. Greiner, S. Klose, K. Reinsch +23
We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. We establish the polarization light curve, detect susta…
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…
Beaming and Jets in GRBs
Re'em Sari
The origin of GRBs have been a mystery for almost 30 years. The afterglow observed in the last few years enabled redshift determination for a handful of bursts, and the cosmologica…
Hydrodynamics of GRB After-Glow
Re'em Sari
The detection of delayed emission at X-ray optical and radio wavelengths, ``after-glow'', suggests that the relativistic shell which emitted the initial GRB due to internal shocks…
Implication of Temporal Structure in GRB
Tsvi Piran, Re'em Sari
The highly variable temporal structure observed in most GRBs provides us with unexpected clues. We show that variable GRBs cannot be produced by external shocks models and conseque…
Hydrodynamic Time Scales and Temporal Structure in GRBs
Re'em Sari, Tsvi Piran
We calculate the hydrodynamic time scales for a spherical ultra-relativistic shell that is decelerated by the ISM and discuss the possible relations between these time scales and t…
