Turbulent processes and mean-field dynamo

Axel Brandenburg, Detlef Elstner, Youhei Masada +1

Mean-field dynamo theory has important applications in solar physics and galactic magnetism. We discuss some of the many turbulence effects relevant to the generation of large-scal…

Alpha tensor and dynamo excitation in turbulent fluids with anisotropic conductivity fluctuations

Oliver Gressel, Günther Rüdiger, Detlef Elstner

A mean-field theory of the electrodynamics of a turbulent fluid is formulated under the assumption that the molecular electric conductivity is correlated with the turbulent velocit…

On the Combined Role of Cosmic Rays and Supernova-Driven Turbulence for Galactic Dynamos

Abhijit B. Bendre, Detlef Elstner, Oliver Gressel

Large-scale coherent magnetic fields observed in the nearby galaxies are thought to originate by a mean-field dynamo. This is governed via the turbulent electromotive force (EMF, $…

Various scenarios for the equatorward migration of sunspots

Detlef Elstner, Yori Fournier, Rainer Arlt

The profile of the differential rotation together with the sign of the alpha-effect determine the dynamo wave direction. In early models of the solar dynamo the dynamo wave often l…

On the spatial and temporal non-locality of dynamo mean-field effects in supersonic interstellar turbulence

Oliver Gressel, Detlef Elstner

The interstellar medium of the Milky Way and nearby disk galaxies harbours large-scale coherent magnetic fields of Microgauss strength, that can be explained via the action of a me…

Turbulent transport coefficients in galactic dynamo simulations using singular value decomposition

Abhijit B. Bendre, Kandaswamy Subramanian, Detlef Elstner +1

Coherent magnetic fields in disc galaxies are thought to be generated by a large-scale (or mean-field) dynamo operating in their interstellar medium. A key driver of mean magnetic…
