The universe is magnetized on all scales probed so far. On the largest scales, galaxies and
galaxy clusters host magnetic fields at the micro Gauss level coherent on scales up to ten …

We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

Direct images of protoplanets embedded in disks around infant stars provide the key to
understanding the formation of gas giant planets such as Jupiter. Using the Subaru …

Magnetic reconnection, topological changes in magnetic fields, is a fundamental process in
magnetized plasmas. It is associated with energy release in regions of magnetic field …

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 Turbulence affects the structure and motions of nearly all temperature and density
regimes in the interstellar gas. This two-part review summarizes the observations, theory …

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 …

This paper presents a theoretical framework for understanding plasma turbulence in
astrophysical plasmas. It is motivated by observations of electromagnetic and density …

We propose a phenomenological model for incompressible magnetohydrodynamic
turbulence. We argue that nonlinear-wave interaction weakens as the energy cascade …

We report the results of an extensive numerical study of the small-scale turbulent dynamo.
The primary focus is on the case of large magnetic Prandtl numbers Pr m, which is relevant …
