The Energy Distribution of Long Duration GRBS
Tsvi Piran, Pawan Kumar, Alin Panaitescu +1
The energy release in gamma-ray bursts is one of the most interesting clues on the nature of their "inner engines". We show here that the total energy release in GRBs varies by les…
Properties of Relativistic Jets in Gamma-Ray Burst Afterglows
A. Panaitescu, P. Kumar
We extend our calculation of physical parameters of GRB jets by modeling the broadband emission of the afterglows 970508, 980519, 991208, 000926, 000418, and 010222. Together with…
Observational Prospects for Afterglows of Short Duration Gamma-ray Bursts
Alin Panaitescu, Pawan Kumar, Ramesh Narayan
If the efficiency for producing -rays is the same in short duration ($\siml 2$ s) Gamma-Ray Bursts (GRBs) as in long duration GRBs, then the average kinetic energy of short GRBs…
A Jet Model With a Hard Electron Distribution for the Afterglow of GRB 000301c
A. Panaitescu
The parameters of the GRB 000301c afterglow are determined within the usual framework of synchrotron emission from relativistic ejecta, through fits to the available radio-to-optic…
