Modeling of Relativistic Plasmas with a Conservative Discontinuous Galerkin Method
James Juno, Grant Johnson, Alexander Philippov +3
We present a new method for solving the relativistic Vlasov--Maxwell system of equations, applicable to a wide range of extreme high-energy-density astrophysical and laboratory env…
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…
Coherence of Multi-Dimensional Pair Production Discharges in Polar Caps of Pulsars
Alexander Chernoglazov, Alexander Philippov, Andrey Timokhin
We report on the first self-consistent multidimensional particle-in-cell numerical simulations of non-homogeneous pair discharges in polar caps of rotation-powered pulsars. By intr…
The Interplay between accelerated Protons, X-rays and Neutrinos in the Corona of NGC 1068: Constraints from Kinetic Plasma Simulations
Rostom Mbarek, Alexander Philippov, Alexander Chernoglazov +2
We examine properties of accelerated protons potentially responsible for the neutrino excess observed in the direction of NGC 1068, using constraints from kinetic Particle-in-Cell…
High-Energy Radiation and Ion Acceleration in Three-dimensional Relativistic Magnetic Reconnection with Strong Synchrotron Cooling
Alexander Chernoglazov, Hayk Hakobyan, Alexander A. Philippov
We present the results of 3D particle-in-cell (PIC) simulations that explore relativistic magnetic reconnection in pair plasma with strong synchrotron cooling and a small mass frac…
Dynamic alignment and plasmoid formation in relativistic magnetohydrodynamic turbulence
Alexander Chernoglazov, Bart Ripperda, Alexander A. Philippov
We present high resolution 2D and 3D simulations of magnetized decaying turbulence in relativistic resistive magneto-hydrodynamics. The simulations show dynamic formation of large…
Weak Alfvénic turbulence in relativistic plasmas. Part 1. Dynamical equations and basic dynamics of interacting resonant triads
J. M. TenBarge, B. Ripperda, A. Chernoglazov +6
Alfvén wave collisions are the primary building blocks of the non-relativistic turbulence that permeates the heliosphere and low-to-moderate energy astrophysical systems. However,…
Weak Alfvénic turbulence in relativistic plasmas II: Current sheets and dissipation
B. Ripperda, J. F. Mahlmann, A. Chernoglazov +6
Alfvén waves as excited in black hole accretion disks and neutron star magnetospheres are the building blocks of turbulence in relativistic, magnetized plasmas. A large reservoir o…
On the Radio Image of Relativistic Jets -- I. Internal Structure, Doppler Boosting, and Polarization Maps
A. V. Chernoglazov, V. S. Beskin, V. I. Pariev
In this first paper from forthcoming series of works devoted to radio image of relativistic jets from active galactic nuclei the role of internal structure of a flow is discussed.…
On the deceleration of relativistic jets in active galactic nuclei I: Radiation drag
V. S. Beskin, A. V. Chernoglazov
Deceleration of relativistic jets from active galactic nuclei (AGNs) detected recently by MOJAVE team is discussed in connection with the interaction of the jet material with the e…
