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…
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…
Magnetogenesis in a collisionless plasma: from Weibel instability to turbulent dynamo
Muni Zhou, Vladimir Zhdankin, Matthew W. Kunz +2
We report on a first-principles numerical and theoretical study of plasma dynamo in a fully kinetic framework. By applying an external mechanical force to an initially unmagnetized…
Intermittency and electron heating in kinetic-Alfvén-wave turbulence
Muni Zhou, Zhuo Liu, Nuno F. Loureiro
We report analytical and numerical investigations of sub-ion-scale turbulence in low-beta plasmas, focusing on the spectral properties of the fluctuations and electron heating. In…
Multi-scale dynamics of magnetic flux tubes and inverse magnetic energy transfer
Muni Zhou, Nuno F. Loureiro, Dmitri A. Uzdensky
We report on an analytical and numerical study of the dynamics of a three-dimensional array of identical magnetic flux tubes in the reduced-magnetohydrodynamic description of the p…
Magnetic island merger as a mechanism for inverse magnetic energy transfer
Muni Zhou, Pallavi Bhat, Nuno F. Loureiro +1
Magnetic energy transfer from small to large scales due to successive magnetic island coalescence is investigated. A solvable analytical model is introduced and shown to correctly…
