Turbulence and Transport During Guide-Field Reconnection at the Magnetopause

, 2019
We analyze the development and influence of turbulence in three-dimensional particle-in-cell simulations of guide-field magnetic reconnection at the magnetopause with parameters based on observations of an electron diffusion region by the Magnetospheric ...

Asymmetries observed in Saturn's magnetopause geometry [PDF]

Geophysical Research Letters, 2015
AbstractFor over 10 years, the Cassini spacecraft has patrolled Saturn's magnetosphere and observed its magnetopause boundary over a wide range of prevailing solar wind and interior plasma conditions. We now have data that enable us to resolve a significant dawn‐dusk asymmetry and find that the magnetosphere extends farther from the planet on the ...

Observations of the Magnetopause Reconnection Ion Diffusion Region With High‐Density O+ Ions During the May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on high‐resolution measurements from NASA's Magnetospheric Multiscale mission (MMS), we present the first direct observation of an ion diffusion region (IDR) with high number density O+ ions within dayside magnetopause reconnection during the May 2024 superstorm. The O+ ion density reaches a high value of ∼3.3 cm−3.

Cold ions of ionospheric origin observed at the dayside magnetopause and their effects on magnetic reconnection [PDF]

, 2015
Thesis (Ph.D.) University of Alaska Fairbanks, 2015Magnetic reconnection at the dayside magnetopause is one of the most important mechanisms that efficiently transfers solar wind particles, momentum, and energy into the magnetosphere.

Frequency‐Dependent Latitudinal Distributions of Plasmaspheric Plume Hiss Directionality and Amplitude

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Plasmaspheric plume hiss plays a crucial role in shaping Earth's electron radiation belts and influencing magnetosphere–ionosphere energy coupling. However, its generation mechanism remains contested between cyclic‐linear and localized‐nonlinear models. By analyzing over 64,000 high‐resolution plume hiss wave segments from the Van Allen Probes

Jupiter's X-ray and EUV auroras monitored by Chandra, XXM-Newton, and Hisaki satellite [PDF]

, 2016
Jupiter's X-ray auroral emission in the polar cap region results from particles which have undergone strong field-aligned acceleration into the ionosphere.

Magnetopause Boundary Layers in Low Mach CME‐Driven Storm Environment

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Magnetopause boundary layers (BLs) play an important role mediating plasma and energy exchange between the solar wind/magnetosheath and Earth's magnetosphere. Energy exchange across the magnetopause is enhanced during storms, yet little work has been done investigating BLs during storms.

Prediction of Axial Asymmetry in Jovian Magnetopause Reconnection

Geophysical Research Letters, 2023
We show the possible existence of a significant axial asymmetry in the reconnection separator at the Jovian magnetopause using first‐principle, physics‐based global simulations. Under eastward interplanetary magnetic field (IMF) conditions near Jupiter's

A Physics‐Informed Neural Network Approach to the Gannon Storm

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Extreme geomagnetic storms, such as the May 2024 Gannon event, pose significant risks to technological infrastructure, requiring robust forecasting models. Here, we apply Physics‐Informed Neural Networks (PINNs) to the Burton equation to model the storm's ring current dynamics by studying the temporal evolution of the SuperMAG SMR index during
