The Slow Decay of Some Radio Afterglows, a Puzzle for the Simplest GRB Fireball Model
A. Panaitescu, P. Kumar
Abridged: The decay of half of the GRB radio afterglows with long temporal monitoring is significantly slower than at optical frequencies, contrary to what is expected in the simpl…

The Jet Angular Profile and the Afterglow Light Curves
Jonathan Granot, Pawan Kumar, Tsvi Piran
We investigate how the angular structure of GRB jets effects the afterglow light curves at different viewing angles, , from the jet symmetry axis. A numerical hydrodynamical…

The Effect of Angular Structure of Gamma-Ray Burst Outflows on the Afterglow Emission
A. Panaitescu, P. Kumar
We investigate analytically the effect of an anisotropic distribution of the kinetic energy within a relativistic fireball on the decay of the afterglow emission, focusing on axial…
