The current understanding of astrophysical magnetic fields is reviewed, focusing on their
generation and maintenance by turbulence. In the astrophysical context this generation is …

▪ Abstract Interstellar turbulence has implications for the dispersal and mixing of the
elements, cloud chemistry, cosmic ray scattering, and radio wave propagation through the …

These lecture notes are based on a tutorial given in 2017 at a plasma physics winter school
in Les Houches. Their aim is to provide a self-contained graduate-student level introduction …

We present a new version of the MURaM radiative magnetohydrodynamics (MHD) code that
allows for simulations spanning from the upper convection zone into the solar corona. We …

Several recent advances in turbulent dynamo theory are reviewed. High resolution
simulations of small-scale and large-scale dynamo action in periodic domains are compared …

Recent progress in astrophysical hydromagnetic turbulence is being reviewed. The physical
ideas behind the now widely accepted Goldreich–Sridhar model and its extension to …

Recent advances in mean-field theory are reviewed and applications to the Sun, late-type
stars, accretion disks, galaxies and the early Universe are discussed. We focus particularly …

The nonlinear theory of a “shear-current” effect in a nonrotating and nonhelical
homogeneous turbulence with an imposed mean velocity shear is developed. The shear …

There is growing consensus that feedback from active galactic nuclei (AGN) is the main
mechanism responsible for stop** cooling flows in clusters of galaxies. AGN are known to …

Abstract Decades ago S. Lundquist, S. Chandrasekhar, PH Roberts and RJ Tayler first
posed questions about the stability of Taylor–Couette flows of conducting material under the …
