Synchrotron-Regulated Relativistic Magnetohydrodynamic Turbulence: Emission, Polarization, and Faraday Rotation

Xiaochen Sun, Luca Comisso, Lorenzo Sironi +2

Relativistic magnetized plasmas in many high-energy astrophysical systems are both turbulent and strongly radiative, yet their nonlinear dynamics and radiative outcomes remain poor…

Particle Acceleration in Magnetized Shear-Driven Turbulence

Mingxuan Liu, Mateusz Ruszkowski, Ellen Zweibel +5

Shear flows, ubiquitous in space and astrophysical plasmas, can accelerate particles through turbulence excited by the Kelvin-Helmholtz instability. We present the first numerical…

Magnetohydrodynamic-guiding-center-particle-in-cell Method for Multiscale Plasma Kinetic Simulations

Zitao Hu, Xue-Ning Bai, Xiaochen Sun

We present the formulation, algorithm and numerical tests of the magnetohydrodynamic-particle-in-cell (MHD-PIC) method with particles treated under the guiding center approximation…

Linear Analysis and Simulations of the Cosmic-Ray Streaming Instability: the Importance of Oblique Waves

Shuzhe Zeng, Xue-Ning Bai, Xiaochen Sun

Cosmic-ray (CR) streaming instability (CRSI) is believed to play an important role in CR transport and CR feedback to galaxies. It drives the growth of magnetohydrodynamic (MHD) wa…

Kinetic simulations of the cosmic ray pressure anisotropy instability: cosmic ray scattering rate in the saturated state

Xiaochen Sun, Xue-Ning Bai, Xihui Zhao

Cosmic ray (CR) feedback plays a vital role in shaping the formation and evolution of galaxies through their interaction with magnetohydrodynamic waves. In the CR self-confinement…

The Magnetohydrodynamic-Particle-In-Cell Module in Athena++: Implementation and Code Tests

Xiaochen Sun, Xue-Ning Bai

We present a new magnetohydrodynamic-particle-in-cell (MHD-PIC) code integrated into the Athena++ framework. It treats energetic particles as in conventional PIC codes while the re…

Particle Diffusion and Acceleration in Magnetorotational Instability Turbulence

Xiaochen Sun, Xue-Ning Bai

Hot accretion flows contain collisionless plasmas that are believed to be capable of accelerating particles to very high energies, as a result of turbulence generated by the magnet…
