Anisotropic Cosmic Ray Transport resulting from Magnetic Mirroring and Resonant Curvature Scattering
The transport of cosmic rays through turbulent astrophysical plasmas still constitutes an open problem. Building on recent progress, we study the combined effect of magnetic mirroring and resonant curvature scattering on parallel and perpendicular transport. We conduct test particle simulations in snapshots of an anisotropic magnetohydrodynamics simulation, and record magnetic moment variation and field line curvature around pitch angle reversals. We find for strongly magnetized particles that …
