Prospects for ultra-high-energy particle acceleration at relativistic shocks

Zhi-Qiu Huang, Brian Reville, John G. Kirk +1

We study the acceleration of charged particles by ultra-relativistic shocks using test-particle Monte-Carlo simulations. Two field configurations are considered: (i) shocks with un…

Particle acceleration at ultrarelativistic, perpendicular shock fronts

John G. Kirk, Brian Reville, Zhi-Qiu Huang

Using an eigenfunction expansion to solve the transport equation, complemented by Monte-Carlo simulations, we show that ultrarelativistic shocks can be effective particle accelerat…

The implications of TeV detected GRB afterglows for acceleration at relativistic shocks

Zhi-Qiu Huang, John Kirk, Gwenael Giacinti +1

Motivated by the detection of very high energy gamma-rays deep in the afterglow emission of a gamma-ray burst, we revisit predictions of the maximum energy to which electrons can b…

Electron Acceleration in the Crab Nebula

Gwenael Giacinti, John G. Kirk

We study electron and positron acceleration at the termination shock of a striped pulsar wind. Drift motion along the shock surface keeps either electrons or positrons -but not bot…

Inductive acceleration of ions in Poynting-flux dominated outflows

John G. Kirk, Gwenael Giacinti

Two-fluid (electron-positron) plasma modelling has shown that inductive acceleration can convert Poynting flux directly into bulk kinetic energy in the relativistic flows driven by…

TeV-PeV Cosmic-Ray Anisotropy and Local Interstellar Turbulence

Gwenael Giacinti, John G. Kirk

We calculate the shape of the large-scale anisotropy of TeV-PeV cosmic-rays (CR) in different models of the interstellar turbulence. In general, the large-scale CR anisotropy (CRA)…
