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…
An outflow from the X-ray corona as the origin of millimeter emission from radio-quiet AGN
A. Hankla, A. Philippov, R. Mbarek +4
Recent observations of radio-quiet active galactic nuclei (RQAGN) have shown the presence of millimeter emission, whose origin remains unknown, from within parsec scales of the cen…
Driven Collisionless Reconnection of Force-free Flux Tubes: From Onset to Coalescence
Camille Granier, Daniel Groselj, Luca Comisso +1
We investigate the onset of driven collisionless reconnection and plasmoid formation in a magnetically dominated pair plasma, using 2D Particle-in-Cell simulations. Two force-free…
Leaking Outside the Box: Kinetic Turbulence with Cosmic-Ray Escape
Evgeny A. Gorbunov, Daniel Grošelj, Fabio Bacchini
We study particle acceleration in strongly turbulent pair plasmas using novel 3D Particle-in-Cell simulations, featuring particle injection from an external heat bath and diffusive…
