A general scheme for modeling gamma-ray burst prompt emission
Pawan Kumar, Erin McMahon, UT Austin
We describe a general method for modeling gamma-ray burst prompt emission. We find that for the burst to be produced via the synchrotron process unphysical conditions are required…
The nature of the outflow in gamma-ray bursts
P. Kumar, E. McMahon, A. Panaitescu +9
The Swift satellite has enabled us to follow the evolution of gamma-ray burst (GRB) fireballs from the prompt gamma-ray emission to the afterglow phase. The early x-ray and optical…
A unified picture for gamma-ray burst prompt and X-ray afterglow emissions
P. Kumar, E. McMahon, S. D. Barthelmy +5
Data from the Swift satellite has enabled us for the first time to provide a complete picture of the gamma-ray burst emission mechanism and its relationship with the early afterglo…
Reverse Shock Emission as a Probe of GRB Ejecta
E. McMahon, P. Kumar, T. Piran
We calculate the reverse shock (RS) synchrotron emission in the optical and the radio wavelength bands from electron-positron pair enriched gamma-ray burst ejecta with the goal of…
Prompt Gamma-ray and Early Afterglow Emission in the External Shock Model
E. McMahon, P. Kumar, A. Panaitescu
We describe our attempt to determine if gamma-ray burst (GRB) and afterglow emissions could both arise in external shocks for simple GRBs--bursts consisting of just a few peaks in…
GRBlog: A Database for Gamma-Ray Bursts
R. Quimby, E. McMahon, J. Murphy
GRBlog is an on-line database providing researchers with quick access to all information reported in the GCN Circulars. Users of the GRBlog web site (grad40.as.utexas.edu/grblog.ph…
