Statistical Distributions of Plasma Density and Pressure in the Jovian Plasma Sheet

The Astrophysical Journal
The Jovian plasma sheet is a key region of the Jovian magnetosphere populated by a mix of warm and hot plasma. It is the main channel for radial transport of mass and energy in the Jovian magnetosphere and provides a favorable environment for magnetic ...

The Mother's Day Storm of 2024 Triggered the Strongest Nighttime Radiative Emission of the SABER Era

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The response of Nitric Oxide (NO) 5.3 µm infrared radiative emission to the 2024 Mother's Day storm is investigated by utilizing Sounding of Atmosphere using Broadband Emission Radiometry (SABER) observations onboard the Thermosphere‐Ionosphere‐Mesosphere Energetics and Dynamics (TIMED) satellite.

Growth of Auroral Structures, Vortex Formation, Turbulence Transition, and Energy Cascade in Alfvénic Magnetosphere‐Ionosphere Coupling

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Magnetohydrodynamic simulations of the Alfvénic magnetosphere‐ionosphere (M‐I) coupling reveal a comprehensive picture of nonlinear development of the feedback instability, demonstrating spontaneous growth of auroral structures of density and current enhancements, vortex formation, turbulence transition, and energy cascade.

Possible role of magnetic reconnection in the electromagnetic counterpart of binary black hole merger

, 2018
We propose a qualitative scenario to interpret the argued association between the direct measurement of the gravitational wave event GW150914 by Laser Interferometer Gravitational Wave Observatory (LIGO)-Virgo collaborations and the hard $X$-ray ...

Auroral Asymmetry Associated With the South Atlantic Anomaly

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The South Atlantic anomaly (SAA) exerts a weakening effect on magnetic field strength on Earth, however, little is known of its effect on the auroral spatial distribution and temporal evolution. Using Defense Meteorological Satellite Program/Special Sensor Ultraviolet Spectrographic Imager ultraviolet data spanning 2016–2023, we investigated ...

Energetic Electron Enhancements Near the Dayside Magnetopause: Outward Radial Transport Due To Asymmetric Drift‐Orbit Bifurcation

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The magnetopause boundary layer often exhibits flux enhancements in ≳30 $\gtrsim 30$ keV electrons. Intriguingly, these enhancements frequently occur in the afternoon sector, which is typically magnetopause‐shadowed. They are usually attributed to local production by dayside reconnection, wave‐particle interactions, or radial diffusion by ...

Electron Energization by Dispersive Alfvén Waves in the Cusp

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The propagation of kinetic Alfvén waves (assumed sourced from intermittent dayside reconnection) is investigated with a gyrofluid‐kinetic electron model compared with Cluster observations. These observations reveal electron distributions that are preferentially field‐aligned or field‐opposed, with signatures that are unidirectional or ...
