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…

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…
