Guide-Field-mediated Multiscale Instabilities in Relativistic Reconnection
Pranab J Deka, Fabio Bacchini, Muni Zhou +1
We investigate magnetic-energy dissipation, current-sheet dynamics, and nonthermal particle acceleration in three-dimensional relativistic reconnection in an electron--ion plasma w…
Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. I: Curvilinear Special Relativistic Module
Hayk Hakobyan, Ludwig M. Böss, Yangyang Cai +8
Entity is a new-generation, fully open-source particle-in-cell (PIC) code developed to overcome key limitations in astrophysical plasma modeling, particularly the extreme separatio…
Suppression of inverse magnetic energy transfer in collisionless marginally magnetized plasmas
Zhuo Liu, Muni Zhou, Nuno F. G. Loureiro
We investigate the inverse cascade of magnetic energy in decaying, collisionless plasmas with moderate to high- values via first-principles numerical simulations and analytical…
Radiative relativistic turbulence as an in situ pair-plasma source in blazar jets
John Mehlhaff, Muni Zhou, Vladimir Zhdankin
As powerful gamma-ray engines, blazars -- relativistic plasma jets launched toward Earth from active galactic nuclei -- are manifestly high-energy particle accelerators. Yet, exact…
Electron-only reconnection and inverse magnetic-energy transfer at sub-ion scales
Zhuo Liu, Caio Silva, Lucio M. Milanese +3
We derive, and validate numerically, an analytical model for electron-only magnetic reconnection applicable to strongly magnetized plasmas. Our model predicts sub-ion-scale reconne…
