PIC simulations of nonrelativistic high-Mach-number oblique shocks propagating in a turbulent medium
Karol Fulat, Eloise Moore, Mahmoud Alawashra +4
Collisionless shocks are common in astrophysical systems and stand as sites of particle acceleration. While particles at perpendicular shocks may not return to the upstream region,…
MeV cosmic-ray electrons modify the TeV pair-beam plasma instability
Mahmoud Alawashra, Yuanyuan Yang, Christopher M. Hirata +2
Relativistic pair beams created in the intergalactic medium (IGM) by TeV gamma rays from blazars are expected to produce a detectable GeV-scale electromagnetic cascade, but the cas…
Marginal Role of the Electrostatic Instability in the GeV-scale Cascade Flux from 1ES 0229+200
Mahmoud Alawashra, Ievgen Vovk, Martin Pohl
Relativistic pair beams produced in the intergalactic medium (IGM) by TeV gamma rays from blazars are expected to generate a detectable GeV-scale electromagnetic cascade, yet this…
Nonlinear feedback of the electrostatic instability on the blazar-induced pair beam and GeV cascade
Mahmoud Alawashra, Martin Pohl
Relativistic pair beams produced in the cosmic voids by TeV gamma rays from blazars are expected to produce a detectable GeV-scale cascade that is missing in the observations. The…
Suppression of the TeV pair-beam plasma instability by a tangled weak intergalactic magnetic field
Mahmoud Alawashra, Martin Pohl
We study the effect of a tangled sub-fG level intergalactic magnetic field (IGMF) on the electrostatic instability of a blazar-induced pair beam. Sufficiently strong IGMF may signi…
