Bulk Motions in the Black Hole Jet Sheath as a Candidate for the Comptonizing Corona
Navin Sridhar, Bart Ripperda, Lorenzo Sironi +2
Using two-dimensional general relativistic resistive magnetohydrodynamic simulations, we investigate the properties of the sheath separating the black hole jet from the surrounding…
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…
Neutrino and pair creation in reconnection-powered coronae of accreting black holes
D. Karavola, M. Petropoulou, D. F. G. Fiorillo +2
A ubiquitous feature of accreting black hole systems is their hard X-ray emission which is thought to be produced through Comptonization of soft photons by electrons and positrons…
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…
Machine-Learning Characterization of Intermittency in Relativistic Pair Plasma Turbulence: Single and Double Sheet Structures
Trung Ha, Joonas Nättilä, Jordy Davelaar +1
The physics of turbulence in magnetized plasmas remains an unresolved problem. The most poorly understood aspect is intermittency -- spatio-temporal fluctuations superimposed on th…
Electrostatic Waves and Electron Holes in Simulations of Low-Mach Quasi-Perpendicular Shocks
Artem Bohdan, Aaron Tran, Lorenzo Sironi +1
Collisionless low Mach number shocks are abundant in astrophysical and space plasma environments, exhibiting complex wave activity and wave-particle interactions. In this paper, we…
