Cross‐Calibration of Energetic Electron Flux Measurements From the Cluster and THEMIS Missions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Energetic electrons in Earth's magnetosphere play a critical role in space weather processes and pose risks to spacecraft electronics. Combining measurements from multiple missions, such as Cluster and Time History of Events and Macroscale Interactions during Substorms (THEMIS), enhances our understanding of these populations but requires ...

Parametric Dependence of Linear and Nonlinear Growth of Whistler‐Mode Chorus Waves

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We calculated the linear and nonlinear growth rates of whistler‐mode chorus waves with relativistic treatment across different wave frequencies and investigated their dependence on the associated parameters, including background magnetic field strength, cold electron density, and energetic electron temperature.

Relativistic Electron Acceleration and the “Ankle” Spectral Feature in Earth’s Magnetotail Reconnection

The Astrophysical Journal Letters
Electrons are accelerated to high, nonthermal energies during explosive energy-release events in space, such as magnetic reconnection. However, the properties and acceleration mechanisms of relativistic electrons directly associated with the reconnection

The physics and chemistry of dusty plasmas: A laboratory and theoretical investigation [PDF]

Theoretical work on dusty plasmas was conducted in three areas: collective effects in a dusty plasma, the role of dusty plasmas in cometary atmospheres, and the role of dusty plasmas in planetary atmospheres (particularly in the ring systems of the giant

Geoeffectivity of Solar Wind Heavy Ions

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract The influence of solar wind properties, such as the southward interplanetary magnetic field, on geomagnetic activity has been well established. However, the role of heavy ions (i.e., particles heavier than protons) in the solar wind on geomagnetic storms is not fully understood.

A Statistical Study of the Distant Magnetotail Under Northward Interplanetary Magnetic Field

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We perform a statistical analysis of the plasma and magnetic field parameters in the magnetotail at XGSE∼ ${\mathrm{X}}_{\mathit{GSE}}\ \sim $ −60 RE ${\mathrm{R}}_{E}$ observed by ARTEMIS under both northward and southward interplanetary magnetic field (IMF) conditions.

A Study of Slow-mode Shocks in the Near-Earth Magnetotail with MMS Observations and Hybrid Simulations

The Astrophysical Journal
The structure of the magnetic reconnection boundary, particularly the presence of slow-mode shocks in the near-Earth magnetotail was studied by using magnetospheric multiscale (MMS) observations and 2.5D hybrid simulations. A total of 51 crossings of MMS

Local Time Dependence of High‐Latitude Pc5 Wave Activity Driven by Interplanetary Shocks and Foreshock Transients, Using a New ULF Index

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract We present a study of ground‐based Pc5 ultra‐low frequency (ULF) wave response to over 400 interplanetary (IP) shocks and 18 foreshock transients. We investigated the local time dependence of magnetospheric Pc5 wave power generated by IP shocks and foreshock transients and whether this dependence is related to the impact angle of IP shocks and

Turbulent Magnetic Reconnection as an Acceleration Mechanism in Earth’s Magnetotail

The Astrophysical Journal
Using electric and magnetic fields measured by the Magnetospheric Multiscale (MMS) mission, we construct a test-particle simulation of a turbulent magnetic reconnection region to investigate observed ion acceleration. We identify three types of energized
