Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

Observation of Interchange Reconnection on Mars

The Astrophysical Journal, 2023
Without a global dipole magnetic field, Mars has magnetic anomalies, i.e., crustal fields, in the southern hemisphere and interesting flexible magnetic fields in the magnetotail.

Ventriculoperitoneal Shunt Malfunction: The Importance of Topogram Image Observation

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Disconnection of a ventriculoperitoneal shunt is a serious complication. The “sunset eye” sign is an important indicator of hydrocephalus. Observation of a CT topogram is an important diagnostic measure and should not be overlooked, and good care of the ventriculoperitoneal shunt should also be taken.

Achieving fast reconnection in resistive MHD models via turbulent means [PDF]

Nonlinear Processes in Geophysics, 2012
Astrophysical fluids are generally turbulent and this preexisting turbulence must be taken into account for models of magnetic reconnection in astrophysical, solar or heliospheric environments.

Flow-turbulence interaction in magnetic reconnection

, 2011
Roles of turbulence in the context of magnetic reconnection are investigated with special emphasis on the mutual interaction between flow (large-scale inhomogeneous structure) and turbulence. In order to evaluate the effective transport due to turbulence,

Constraining Electron‐Impact Ionization of O2 Through UV Aurora Observations at Ganymede

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract While photoionization rates of Ganymede's O2 ${\mathrm{O}}_{2}$ dominated atmosphere are well constrained, the contribution of electron‐impact ionization is rather uncertain. Previous quantitative estimates have relied on assumptions about densities and energy distributions of precipitating electrons, or on rare spacecraft measurements that ...

Solar Wind‐Magnetosphere‐Ionosphere Coupling During the October 2024 Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Two geomagnetic storms occurred in October 2024 (Oct 6‐9 and 10–12), driven by the impact of a series of interplanetary coronal mass ejections on the magnetosphere. The first was a moderate storm, with peak Sym‐H near −150 nT, whereas the second was intense, Sym‐H reaching −340 nT.

Observations of High‐Resolution Two‐Dimensional Ionospheric Flow Dynamics Associated With Poleward Boundary Intensifications

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Poleward boundary intensifications (PBIs) are one of the most common auroral disturbances and have been shown to play a key role in substorm dynamics. PBIs are commonly interpreted as the ionospheric signature of magnetotail reconnection, providing insight into X‐line evolution.

Bidirectional outflows as evidence of magnetic reconnection leading to a solar microflare

, 2016
Magnetic reconnection is a rapid energy release process that is believed to be responsible for flares on the Sun and stars. Nevertheless, such flare-related reconnection is mostly detected to occur in the corona, while there have been few studies ...

Secondary Reconnection Between Interlinked Flux Tubes Driven by Magnetic Reconnection With a Short X‐Line

Geophysical Research Letters
A three‐dimensional particle‐in‐cell simulation is performed to study secondary reconnection between two interlinked flux tubes produced by neighboring guide field reconnection x‐lines.
