Probing Thermal Electrons in Gamma-Ray Burst Afterglows

The Astrophysical Journal
Particle-in-cell simulations have unveiled that shock-accelerated electrons do not follow a pure power-law distribution, but have an additional low-energy “thermal” part, which owns a considerable portion of the total energy of the electrons ...

Gamma-Ray Burst Pulse Structures and Emission Mechanisms

The Astrophysical Journal
The prompt phase X-ray and gamma-ray light curves of gamma-ray bursts (GRBs) exhibit erratic and complex behaviors, often with multiple pulses. The temporal shape of the individual pulses is often modeled as “fast rise exponential decay” (FRED). Here, we

Gamma-Ray Burst Pulses and Lateral Jet Motion

The Astrophysical Journal
We propose that gamma-ray burst (GRB) pulses are produced when highly relativistic jets sweep across an observer’s line of sight. We hypothesize that axisymmetric jet profiles, coupled with special relativistic effects, produce the time-reversed ...
