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…
-- 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…
Polarized anisotropic synchrotron emission and absorption and its application to Black Hole Imaging
Alisa Galishnikova, Alexander Philippov, Eliot Quataert
Low-collisionality plasma in a magnetic field generically develops anisotropy in its distribution function with respect to the magnetic field direction. Motivated by the applicatio…
Cosmic ray transport in large-amplitude turbulence with small-scale field reversals
Philipp Kempski, Drummond B. Fielding, Eliot Quataert +4
The nature of cosmic ray (CR) transport in the Milky Way remains elusive. The predictions of current micro-physical CR transport models in magneto-hydrodynamic (MHD) turbulence are…
Collisionless accretion onto black holes: dynamics and flares
Alisa Galishnikova, Alexander Philippov, Eliot Quataert +3
We study the accretion of collisionless plasma onto a rotating black hole from first principles using axisymmetric general-relativistic particle-in-cell simulations. We carry out a…
Tearing instability and current-sheet disruption in the turbulent dynamo
Alisa K. Galishnikova, Matthew W. Kunz, Alexander A. Schekochihin
Turbulence in a conducting plasma can amplify seed magnetic fields in what is known as the turbulent, or small-scale, dynamo. The associated growth rate and emergent magnetic-field…
