Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Auroral Emissions on Ganymede: New Constraints on Their Electron Energy Dependence

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Auroral emissions on Ganymede provide critical insights into its magnetospheric dynamics and atmospheric composition. Using a physics‐based atmospheric model with recent atmospheric observations and laboratory measurements of electron‐impact cross‐sections, this study revisits and significantly refines the relationship between auroral emission

Microphysics in Astrophysical Plasmas [PDF]

Space Science Reviews, 2013
Although macroscale features dominate astrophysical images and energetics, the physics is controlled through microscale transport processes (conduction, diffusion) that mediate the flow of mass, momentum, energy, and charge. These microphysical processes manifest themselves in key (all) boundary layers and also operate within the body of the plasma ...

Finding Local Parallel Electric Fields in Magnetotail Reconnection Using a Two‐Spacecraft Method

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the use of a novel two‐spacecraft Liouville‐mapping method using data from the Magnetospheric Multiscale mission to determine local magnetic‐field‐aligned (parallel) electric fields in the Earth's magnetotail. The method detects the presence of local acceleration potentials by mapping phase‐space density between electron ...

Short‐Term Variability of Jupiter's Satellite Footprints as Spotted by JWST

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We present the main Alfvén wing (MAW) spots of Io and Europa as observed by the Near‐Infrared Spectrograph onboard the James Webb Space Telescope. These auroral footprint features have been measured previously, but only in emission. Here, the derived ionospheric H3+ ${\mathrm{H}}_{3}^{+}$ emission, temperature and column density are reported ...

Plasma in Astrophysics

Physica Scripta, 1982
Two examples of plasma phenomena of importance to astrophysics are reviewed. These are examples where astrophysical understanding hinges on further progress in plasma physics understanding. The two examples are magnetic reconnection and the collisionless interaction between a population of energetic particles and a cooler gas or plasma, in particular ...

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood. Here, we employ 2.5‐D particle‐in‐cell simulations to investigate IAWs in asymmetric magnetopause reconnection involving a cold ion population ...
