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…
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…
Generation of cosmic ray trajectories by a Diffusion Model trained on test particles in 3D magnetohydrodynamic turbulence
Johannes Martin, Jeremiah Lübke, Tianyi Li +3
Models for the transport of high energy charged particles through strong magnetic turbulence play a key role in space and astrophysical studies, such as describing the propagation…
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…
Instantons, fluctuations and singularities in the supercritical stochastic nonlinear Schroedinger equation
Sumeja Burekovic, Tobias Schaefer, Rainer Grauer
Recently, Josserand et al. proposed a stochastic nonlinear Schroedinger model for finite-time singularity-mediated turbulence [Phys. Rev. Fluids 5, 054607 (2020)]. Here, we use ins…
Towards Synthetic Magnetic Turbulence with Coherent Structures
Jeremiah Lübke, Frederic Effenberger, Mike Wilbert +2
Synthetic turbulence is a relevant tool to study complex astrophysical and space plasma environments inaccessible by direct simulation. However, conventional models lack intermitte…
Local Turbulence Simulations for the Multiphase ISM
R. Kissmann, J. Kleimann, H. Fichtner +1
In this paper we show results of numerical simulations for the turbulence in the interstellar medium. These results were obtained using a Riemann solver-free numerical scheme for h…
