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…
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…
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…
The baryon content of magnetically arrested black hole disks and jets
Anthony Chow, Lorenzo Sironi, Bart Ripperda +1
We study the transport of baryons in magnetically arrested accretion flows and relativistic jets using general relativistic magnetohydrodynamic simulations that incorporate a passi…
Magnetic Field Amplification and Particle Acceleration in Weakly Magnetized Trans-relativistic Electron-ion Shocks
Taiki Jikei, Daniel Groselj, Lorenzo Sironi
We investigate the physics of quasi-parallel trans-relativistic shocks propagating in weakly magnetized plasmas by means of long-duration two-dimensional particle-in-cell simulatio…
