Entity -- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. III: Higher-order shape functions & generalized field stencils
Ludwig M. Böss, Arno Vanthieghem, Hayk Hakobyan +2
Modern particle-in-cell (PIC) codes have become an integral tool in plasma astrophysics. As most plasma phenomena grow from initially small instabilities, it is important to ensure…
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…
Superluminal Wave Activation at Relativistic Magnetized Shocks
Jens F. Mahlmann, Logan Eskildsen, Arno Vanthieghem +2
Fast radio bursts (FRBs) are extremely energetic radio transients, some are generated in magnetar magnetospheres and winds. Despite a growing number of observations, their emission…
Relativistically Magnetized Collisionless Shocks in Pair Plasma: I. Solitons, Chaos, and Thermalization
Arno Vanthieghem, Amir Levinson
In this paper, the first in a series, we present a new theoretical model for the global structure and dissipation of relativistically magnetized collisionless shock waves. Quite re…
Generation of Large-scale Magnetic Fields Upstream of Gamma-Ray Burst Afterglow Shocks
Ryan Golant, Arno Vanthieghem, Daniel Groselj +1
The origins of the magnetic fields that power gamma-ray burst (GRB) afterglow emission are not fully understood. One possible channel for generating these fields involves the pre-c…
Electron-Ion Temperature Ratio in Transrelativistic Unmagnetized Shock Waves
Arno Vanthieghem, Vasileios Tsiolis, Frederico Fiuza +3
Weakly magnetized shock waves are paramount to a large diversity of environments, including supernova remnants, blazars, and binary-neutron-star mergers. Understanding the distribu…
