Structure of a collisionless pair jet in a magnetized electron-proton plasma: Flow-aligned magnetic field
Mark Eric Dieckmann, Martin Falk, Peter Steneteg +6
We present the results from a particle-in-cell (PIC) simulation that models the interaction between a spatially localized electron-positron cloud and an electron-ion plasma. The la…
Structure of a collisionless pair jet in a magnetized electron-proton plasma: flow-aligned magnetic field
M E Dieckmann, D Folini, I Hotz +4
We study the effect a guiding magnetic field has on the formation and structure of a pair jet that propagates through a collisionless electron-proton plasma at rest. We model with…
Electrostatic and magnetic instabilities in the transition layer of a collisionless weakly relativistic pair shock
M E Dieckmann, A Bret
Energetic electromagnetic emissions by astrophysical jets like those that are launched during the collapse of a massive star and trigger gamma-ray bursts (GRBs) are partially attri…
Simulation study of the formation of a non-relativistic pair shock
Mark Eric Dieckmann, Antoine Bret
We examine with a particle-in-cell (PIC) simulation the collision of two equally dense clouds of cold pair plasma. The clouds interpenetrate until instabilities set in, which heat…
PIC Simulations of the Temperature Anisotropy-Driven Weibel Instability: Analyzing the perpendicular mode
A Stockem, M E Dieckmann, R Schlickeiser
An instability driven by the thermal anisotropy of a single electron species is investigated in a 2D particle-in-cell (PIC) simulation. This instability is the one considered by We…
Particle-in-cell simulation of a mildly relativistic collision of an electron-ion plasma carrying a quasi-parallel magnetic field: Electron acceleration and magnetic field amplification at supernova shocks
M E Dieckmann, G Murphy, A Meli +1
Plasma processes close to SNR shocks result in the amplification of magnetic fields and in the acceleration of electrons, injecting them into the diffusive acceleration mechanism.…
