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…

Non-relativistic perpendicular shocks modeling young supernova remnants: nonstationary dynamics and particle acceleration at forward and reverse shocks
Volkmar Wieland, Martin Pohl, Jacek Niemiec +2
For parameters that are applicable to the conditions at young supernova remnants, we present results of 2D3V particle-in-cell simulations of a non-relativistic plasma shock with a…
