Astrophysical plasmas have the remarkable ability to preserve magnetic topology, which
inevitably gives rise to the accumulation of magnetic energy within stressed regions …

Magnetic reconnection is a topological rearrangement of magnetic field that occurs on time
scales much faster than the global magnetic diffusion time. Since the field lines break on …

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 …

We calculate the disruption scale, when this range exists. Such a steep 'transition range'is
sometimes observed in short intervals of solar-wind turbulence. The onset of collisionless …

HelioSwarm (HS) is a NASA Medium-Class Explorer mission of the Heliophysics Division
designed to explore the dynamic three-dimensional mechanisms controlling the physics of …

Recent advances in mean-field theory are reviewed and applications to the Sun, late-type
stars, accretion disks, galaxies and the early Universe are discussed. We focus particularly …

We perform numerical simulations of decaying hydrodynamic and magnetohydrodynamic
turbulence. We classify our time-dependent solutions by their evolutionary tracks in …

Laboratory experiments provide a valuable complement to explore the fundamental physics
of space plasmas without the limitations inherent to spacecraft measurements. Specifically …

The spontaneous formation of magnetic islands is observed in driven, antiparallel magnetic
reconnection on the Terrestrial Reconnection Experiment. We here provide direct …

We report in situ observations of an electron diffusion region (EDR) and adjacent separatrix
region in the Earth's magnetotail. We observe significant magnetic field oscillations near the …
