Recent years have witnessed dramatic progress in our understanding of how turbulence
arises and transports angular momentum in astrophysical accretion disks. The key …

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

Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

In this review we will focus on a topic of fundamental importance for both astrophysics and
plasma physics, namely the occurrence of large-amplitude low-frequency fluctuations of the …

This book presents an introduction to, and modern account of, magnetohydrodynamic
(MHD) turbulence, an active field both in general turbulence theory and in various areas of …

A review of the present status of the theory of magnetic reconnection is given. In strongly
collisional plasmas reconnection proceeds via resistive current sheets, ie quasi-stationary …

▪ Abstract We discuss current observational and theoretical knowledge of magnetic fields,
especially the large-scale structure in the disks and halos of spiral galaxies. Among other …

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 …

A numerical model of isotropic homogeneous turbulence with helical forcing is investigated.
The resulting flow, which is essentially the prototype of the α 2 dynamo of mean field …

The solar dynamo continues to pose a challenge to observers and theoreticians.
Observations of the solar surface reveal a magnetic field with a complex, hierarchical …
