Journal ArticleDOI
Astrophysical magnetic fields and nonlinear dynamo theory
TL;DR: The current understanding of astrophysical magnetic fields is reviewed in this paper, focusing on their generation and maintenance by turbulence, where analytical and numerical results are discussed both for small scale dynamos, which are completely isotropic, and for large scale dynamo, where some form of parity breaking is crucial.
Journal ArticleDOI
Galactic Magnetism: Recent developments and perspectives
TL;DR: In this article, it is argued that a turbulent hydromagnetic dynamo of some kind and an inverse cascade of magnetic energy gives the most plausible explanation for the regular galactic magnetic fields.
Journal ArticleDOI
Dynamo-generated Turbulence and Large-Scale Magnetic Fields in a Keplerian Shear Flow
TL;DR: In this article, the nonlinear evolution of magnetized Keplerian shear fields is simulated in a local, three-dimensional model, including the eeects of compressibility and stratiication.
Journal ArticleDOI
The inverse cascade and nonlinear alpha-effect in simulations of isotropic helical hydromagnetic turbulence
TL;DR: In this paper, a numerical model of isotropic homogeneous turbulence with helical forcing is investigated, which produces strong dynamo action with an additional large-scale field on the scale of the box (at wavenumber k = 1; forcing is at k = 5).
Journal ArticleDOI
The case for a distributed solar dynamo shaped by near-surface shear
TL;DR: In this paper, it is argued that the angular velocities of magnetic tracers are compatible with a distributed dynamo that may be strongly shaped by the near-surface shear layer.
