Modelling cosmic-ray transport: magnetised versus unmagnetised motion in astrophysical magnetic turbulence
Jeremiah Lübke, Patrick Reichherzer, Sophie Aerdker +4
Cosmic-ray transport in turbulent astrophysical environments remains a multifaceted problem and, despite decades of study, the impact of complex magnetic field geometry -- evident…

Anisotropic Cosmic Ray Transport in strong MHD Turbulence due to Magnetic Mirroring and Resonant Curvature Scattering
Jeremiah Lübke, Frederic Effenberger, Mike Wilbert +2
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 mirror…

The role of magnetic boundaries in kinematic and self-consistent magnetohydrodynamic simulations of precession-driven dynamo action in a closed cylinder
André Giesecke, Mike Wilbert, Ján Šimkanin +2
We numerically examine dynamo action generated by a flow of an electrically conducting fluid in a precessing cylindrical cavity. We compare a simplified kinematic approach based on…
