On the ergodicity of perpendicular cosmic ray transport
R. C. Tautz
Aims. The random walk of energetic charged particles in turbulent magnetic fields is investigated. Special focus is placed on transport across the mean magnetic field, which had be…

Cosmic-ray acceleration at collisionless astrophysical shocks using Monte-Carlo simulations
M. Wolff, R. C. Tautz
Context. The diffusive shock acceleration mechanism has been widely accepted as the acceleration mechanism for galactic cosmic rays. While self-consistent hybrid simulations have s…

Cosmic-ray diffusion in magnetized turbulence
R. C. Tautz
The problem of cosmic-ray scattering in the turbulent electromagnetic fields of the interstellar medium and the solar wind is of great importance due to the variety of applications…
