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…
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…
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…
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…
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…
Fast radio bursts as precursor radio emission from monster shocks
Arno Vanthieghem, Amir Levinson
It has been proposed recently that the breaking of MHD waves in the inner magnetosphere of strongly magnetized neutron stars can power different types of high-energy transients. Mo…
