Impact of Induced Electric Fields Inside the Magnetopause on Magnetopause Shadowing of Radiation Belt Electrons

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Loss of relativistic electrons with energies above 0.5 MeV through the magnetopause, commonly referred to as magnetopause shadowing, has been extensively investigated using both simulations and observations. However, direct and systematic observational evidence remains limited. In this study, we extend a previously developed magnetopause model

Parallel Collisionless Shocks in Strongly Magnetized Electron–Ion Plasma. I. Temperature Anisotropies

The Astrophysical Journal
Collisionless electron–ion shocks are fundamental to astrophysical plasmas, yet their behavior in strong magnetic fields remains poorly understood.

The Dominant Role of Crustal Fields in Structuring Electromagnetic Environment Within the Martian Dayside Magnetosphere

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Although Mars lacks an intrinsic global dipole magnetic field, the existence of crustal magnetic anomalies in the southern hemisphere causes the Martian magnetosphere to have the hybrid characteristics combining Venus‐like induced and Earth‐like intrinsic types.

Self‐Regulating Feedback Between Field Line Curvature Scattering, Ring Current Pressure, and Magnetic Configuration

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract We incorporate field line curvature (FLC) scattering into a kinetic ring current model two‐way coupled with a global magnetospheric MHD model to investigate its role in SYM‐H prediction and global magnetospheric dynamics. FLC scattering reduces plasma pressure in regions where the ion gyroradius is comparable to the local FLC radius.

Bridging the Gap Between the Earth's Ionosphere and Plasmasphere

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Cold plasma distribution in the ionosphere‐plasmasphere system governs wave‐particle interactions, plasma energization and loss, and radio wave propagation. A longstanding observational gap at altitudes ∼ ${\sim} $800–8,000 km has largely prevented studying the coupled dynamics of the two regions.

Active Flow Control of the Magnetohydrodynamic Flow in an Annular Linear Induction Pump by Modifying the Driving Electromagnetic Field

International Journal of Energy Research
The strong coupling between fluid and electromagnetic field in the annular linear induction pump (ALIP) can gradually amplify small disturbance in the fluid field into large‐scale vortices. The appearance of the vortices seriously affects the efficiency and reliability of the pump.

Cosmic-Ray Feedback from Supernovae in a Parker-unstable Medium

The Astrophysical Journal
Supernova energy drives interstellar medium (ISM) turbulence and can help launch galactic winds. What difference does it make if 10% of the energy is initially deposited into cosmic rays?

Pulsed power accelerator for material physics experiments

Physical Review Special Topics. Accelerators and Beams, 2015
We have developed the design of Thor: a pulsed power accelerator that delivers a precisely shaped current pulse with a peak value as high as 7 MA to a strip-line load.

Laser energy asymmetry-driven deflection of Au plasma jets in half-cylinder target and its interaction with CH corona plasma

Nuclear Fusion
We investigate the formation of deflected gold $(\mathrm{Au})$ jets and their interaction with plastic $(\mathrm{CH})$ corona plasma, relevant to energy imbalances in the hohlraum for indirect drive inertial confinement fusion (ICF).

Sizes of Active Galactic Nucleus Inhomogeneous Disks—Large in Microlensing, Small in Reverberation Mapping

The Astrophysical Journal
Magnetohydrodynamic turbulence can drive significant temperature fluctuations in the accretion disk of an active galactic nucleus (AGN). As a result, the disk can be highly inhomogeneous and has a half-light radius larger than the static Shakura and ...
