Global Three‐Dimensional Simulation of Magnetospheric Dynamics During the Extreme Geomagnetic Storm of 10–11 May 2024

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...

Statistical Mapping of ULF Wave Power in the Vicinity of Earth's Bow Shock Using Cluster Magnetic Field Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ultra‐low frequency (ULF) waves with frequencies 10–140 s are a characteristic feature of the foreshock, playing important roles in transient formation, shock reformation, and particle acceleration. We utilize 23 years of Cluster data to map ULF wave power and compressibility in the vicinity of Earth's bow shock, combining Cluster data with ...

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath

The Astrophysical Journal
The Earth’s magnetosheath serves as a natural laboratory to study the transition of highly turbulent fluctuations. The fundamental information about plasma turbulences can be examined observationally with the help of electron vorticity measurements. This

MP‐DualNet: A Dual‐Branch Deep Learning Approach for Magnetopause Boundary Detection Using Simulated SXI Images

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The Earth's magnetopause is a key boundary governing solar wind–magnetosphere coupling. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission will provide global soft X‐ray imaging of the magnetosphere through solar wind charge exchange (SWCX) emission, offering a new opportunity for remote sensing of magnetopause dynamics ...

Cross‐Scale Energy Transfer and Scale‐to‐Scale Energy Conversion During the Collisionless Magnetic Reconnection

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract This study investigates cross‐scale energy transfer (CET) and scale‐to‐scale energy conversion (SEC) during magnetic reconnection by employing the scale‐filtering approach in a particle‐in‐cell simulation. Our analysis reveals fundamentally distinct CET patterns for electrons and ions. Electron CET is primarily governed by the flow CET.

Ion velocity distributions within the LLBL and their possible implication to multiple reconnections [PDF]

Annales Geophysicae, 2004
We analyze two LLBL crossings made by the Interball-Tail satellite under a southward or variable magnetosheath magnetic field: one crossing on the flank of the magnetosphere, and another one closer to the subsolar point.

Coherent wave activity in Mercury's magnetosheath [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractThis study presents a statistical overview of coherent wave activity in Mercury's magnetosheath. Left‐handed electromagnetic ion cyclotron waves are commonly found behind the quasi‐perpendicular section of the bow shock, where they are present in ~50% of the spacecraft crossings of the magnetosheath.

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

Field‐Aligned Anisotropy of Electrons in Magnetic Hole Behind the Dipolarization Front in the Flow Braking Region

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Magnetic holes (MHs) are magnetic structures characterized by a depression of magnetic field strength and have been frequently observed around dipolarization fronts (DFs), which are characterized by the increase in the magnetic field Bz. Both MHs and DFs are potential contributors to the formation of electron anisotropy.
