Top row: one-dimensional probability density distributions of the magnetic field strength in the direction parallel to the mean magnetic field, B_∥. Second row: the same but for the perpendicular component, B_⊥). Third row: the parallel component of the CR flux, F_∥. Fourth row: the perpendicular component of the CR flux, F_⊥. All variables have been nondimensionalized by the thermal velocities, c_s, and mean plasma densities, ρ₀. The columns show sub-, trans-, and super-Aflvénic runs, from left to right. The color indicates the value of the microphysical CR diffusion coefficient compared to the turbulent diffusion, Pm_c (see Equation (15)), with a pure MHD simulation (no CRs) being run and shown in red.
