Spiral galaxies, including the Milky Way, have large-scale magnetic fields with significant
energy densities. The dominant theory attributes these magnetic fields to a large-scale …

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 …

Jetted astrophysical phenomena with black hole engines, including binary mergers, jetted
tidal disruption events, and X-ray binaries, require a large-scale vertical magnetic field for …

A number of observational and theoretical aspects of solar magnetoconvection are
considered in this review. We discuss recent developments in our understanding of the …

This review of scaling theories of magnetohydrodynamic (MHD) turbulence aims to put the
developments of the last few years in the context of the canonical time line (from Kolmogorov …

We investigate the impact of a mean field model for the α Ω dynamo potentially active in the
postmerger phase of a binary neutron star coalescence. We do so by deriving equations for …

We propose that the strength of angular momentum transport in accretion discs threaded by
net vertical magnetic field is determined by a self-regulation mechanism: the …

Previous studies of the non-linear regime of the magnetorotational instability in one
particular type of shearing box model–unstratified with no net magnetic flux–find that without …

Magnetic fields in galaxies are believed to be the result of dynamo amplification of initially
weak seed fields, reaching equipartition strength inside the interstellar medium. The small …

The magnetorotational instability (MRI) is an important process in sufficiently ionized
accretion discs, as it can create turbulence that acts as an effective viscosity, mediating …
