Gamma-rays from black hole coronae: disentangling the leptonic and hadronic contributions
Sébastien Le Bihan, Daniel Grošelj, Martin Lemoine
IceCube detections of TeV neutrinos from nearby Seyfert galaxies imply, if confirmed, that the accompanying gamma rays are substantially reprocessed down to the MeV range by electr…
Dependence of Particle Acceleration Efficiency on Shock Velocity in Weakly Magnetized Electron-Ion Shocks
Taiki Jikei, Daniel Groselj, Lorenzo Sironi
Using unprecedentedly long 2D particle-in-cell simulations, we study electron and ion acceleration in weakly magnetized quasi-parallel shocks, propagating at velocities ranging fro…
On The Nonthermal Power Laws In Magnetized Turbulent Plasmas
Rostom Mbarek, Daniel Grošelj, Alexander Philippov
Building on recent progress in the understanding of particle transport in magnetized plasmas, we derive a scaling law for the formation of nonthermal spectral tails in mildly and s…
3D Kinetic Simulations of Driven Reconnection in Merging Flux Tubes
Camille Granier, Fabio Bacchini, Daniel Groselj +1
We present 2D and 3D Particle-in-Cell simulations of driven collisionless magnetic reconnection triggered by the compression and merger of two Lundquist-type force-free flux tubes…
Interaction of Strong Electromagnetic Waves with Unmagnetized Pair Plasmas
Navin Sridhar, Emanuele Sobacchi, Lorenzo Sironi +3
We investigate analytically and numerically the interaction of strong electromagnetic waves with unmagnetized pair plasmas. We show that the interaction is governed by a single non…
Particle-in-Cell Methods for Simulations of Sheared, Expanding, or Escaping Astrophysical Plasma
Fabio Bacchini, Evgeny A. Gorbunov, Maximilien Péters de Bonhome +4
Particle-in-Cell (PIC) methods have achieved widespread recognition as simple and flexible approaches to model collisionless plasma physics in fully kinetic simulations of astrophy…
