Description

Gamma-ray bursts are the most extreme cosmic explosions, emitting across the electromagnetic spectrum and detected on timescales from milliseconds to years. Modeling the multi-wavelength, multi-timescale observations of gamma-ray burst afterglows leads to insights into the macrophysics of the relativistic outflows and their environments, and the microphysics of the particles and magnetic fields. In this talk, I will focus on observational progress that has been made recently, in particular in the radio regime, with fast follow-up programs using large interferometers; and new insights into electron acceleration by relativistic shocks from multi-wavelength observations.
