Weibel Instability Driven by Relativistic Pair Jets: Particle Acceleration, Magnetic Field Generation, and Emission
K. -I. Nishikawa, P. Hardee, C. B. Hededal +4
Shock acceleration is a ubiquitous phenomenon in astrophysical plasmas. Plasma waves and their associated instabilities (e.g., Buneman, Weibel and other two-stream instabilities) c…

Collisionless Plasma Shocks. Field Generation and Particle Acceleration
T. Haugboelle, C. B. Hededal, J. T. Frederiksen +1
Gamma ray bursts are among the most energetic events in the known universe. A highly relativistic fireball is ejected. In most cases the burst itself is followed by an afterglow, e…

Magnetic Field Generation and electron acceleration in Collisionless Shocks
C. B. Hededal, J. Trier Frederiksen, T. Haugboelle +1
Using a three dimensional relativistic particle-in-cell code we have performed numerical experiments of plasma shells colliding at relativistic velocities. Such scenarios are found…
