-- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. II: General Relativistic Module
Alisa Galishnikova, Hayk Hakobyan, Alexander Philippov +1
Black hole environments often host plasmas that are fully collisionless or contain intrinsically collisionless regions, including relativistic jets and coronae where particle energ…

Strongly magnetized accretion with low angular momentum produces a weak jet
Alisa Galishnikova, Alexander Philippov, Eliot Quataert +2
We study the spherical accretion of magnetized plasma with low angular momentum onto a supermassive black hole, utilizing global general relativistic magnetohydrodynamic simulation…
