Comparison of magnetic diffusion and reconnection in ideal and resistive relativistic magnetohydrodynamics, ideal magnetodynamics, and resistive force-free electrodynamics
Michael P. Grehan, Tanisha Ghosal, James R. Beattie +3
High-energy astrophysical systems and compact objects are frequently modeled using ideal relativistic magnetohydrodynamic (MHD) or force-free electrodynamic (FFE) simulations, with…

Effective resistivity in relativistic collisionless plasmoid-mediated reconnection
Sebastiaan Selvi, Oliver Porth, Bart Ripperda +3
Magnetic reconnection can power spectacular high-energy astrophysical phenomena by producing non-thermal energy distributions in highly magnetized regions around compact objects. B…

A New Particle Pusher with Hadronic Interactions for Modeling Multimessenger Emission from Compact Objects
Minghao Zou, Hayk Hakobyan, Rostom Mbarek +3
We propose novel numerical schemes based on the Boris method in curved spacetime, incorporating both hadronic and radiative interactions for the first time. Once the proton has los…
