Kinetic simulations of nonrelativistic perpendicular shocks of young supernova remnants. III. Magnetic reconnection

Artem Bohdan, Martin Pohl, Jacek Niemiec +4

Fully kinetic two-dimensional particle-in-cell simulations are used to study electron acceleration at high-Mach-number nonrelativistic perpendicular shocks. SNR shocks are mediated…

A note on the experiment parameters for the non-resonant streaming instability: competition between left and right circularly polarized modes

Chun-Sung Jao, Sergei Vafin, Ye Chen +10

A non-resonant streaming instability driven by cosmic-ray currents, also called Bell's instability, is proposed as a candidate for providing the required magnetic turbulence of eff…

Revisit of non-linear Landau damping for electrostatic instability driven by blazar-induced pair beams

S. Vafin, P. J. Deka, M. Pohl +1

We revisit the effect of non-linear Landau (NL) damping on the electrostatic instability of blazar-induced pair beams, using a realistic pair-beam distribution. We employ a simplif…

Generation of quasi continuous-wave electron beams in an L-band normal conducting pulsed RF injector for laboratory astrophysics experiments

Ye Chen, Gregor Loisch, Matthias Gross +8

We report on an approach to produce quasi continuous-wave (cw) electron beams with an average beam current of milliamperes and a mean beam energy of a few MeV in a pulsed RF inject…

The electrostatic instability for realistic pair distributions in blazar/EBL cascades

S. Vafin, I. Rafighi, M. Pohl +1

This work revisits the electrostatic instability for blazar-induced pair beams propagating through IGM with the methods of linear analysis and PIC simulations. We study the impact…

Plasma effects on relativistic pair beams from TeV blazars: PIC simulations and analytical predictions

Iman Rafighi, Sergei Vafin, Jacek Niemiec +1

Pair beams produced by very high-energy radiation from TeV blazars emit gamma rays in the GeV band by inverse-Compton scattering of soft photons. The observed GeV-band signal is sm…
