Transient distortions of the South Atlantic Anomaly radiation environments driven by electric fields [PDF]
Nature CommunicationsEnergetic electrons in Earth’s inner radiation belt pose significant hazards to spacecraft systems, with the strongest radiation in low-Earth orbit (LEO) mostly confined to the South Atlantic Anomaly (SAA) region.

Local heating of radiation belt electrons to ultra-relativistic energies [PDF]
Nature Communications, 2020 Electrons in the Van Allen radiation belts can have energies in excess of 7 MeV, however, the energization mechanism is debated. Here, the authors show phase space density peaks in magnetic coordinate space as a way of analyzing satellite observations ...

Lightning-induced relativistic electron precipitation from the inner radiation belt [PDF]
Nature CommunicationsThe Earth’s radiation belts are maintained by a number of acceleration, loss and transport mechanisms, and the electron fluxes at any given time are highly variable.

Dynamics of the inner electron radiation belt: A review
Earth and Planetary Physics, 2023 The Van Allen radiation belts are an extraordinary science discovery in the Earth magnetosphere and consist of two electron belts. The inner Van Allen belt contains electrons of 10s to 100s keV; the outer belt consists mainly of 0.1−10 MeV electrons ...

A data assimilation-based forecast model of outer radiation belt electron fluxes
Earth and Planetary Physics, 2023 Because radiation belt electrons can pose a potential threat to the safety of satellites orbiting in space, it is of great importance to develop a reliable model that can predict the highly dynamic variations in outer radiation belt electron fluxes.

Is the Solar Wind Electron Strahl a Seed Population for the Earth’s Electron Radiation Belt?
Frontiers in Astronomy and Space Sciences, 2022 1) Since the outer electron radiation belt is lost on occasion, the radiation belt needs seed electrons to rebuild. 2) The clear candidate for that seed population is energetic substorm-injected electrons in the dipolar magnetosphere.

The 600 keV electron injections in the Earth’s outer radiation belt: A statistical study
Earth and Planetary Physics, 2022 Relativistic electron injections are one of the mechanisms of relativistic (≥0.5 MeV) electron enhancements in the Earth’s outer radiation belt. In this study, we present a statistical observation of 600 keV electron injections in the outer radiation ...

Frontiers in Astronomy and Space Sciences, 2022 Nonlinear processes are involved in both the growth of VLF chorus waves and the energization of radiation belt electrons trapped in the wave potential. Nonlinear theory has led to analytic formulae describing both these processes.

Geophysical Monograph Series, Page 487-501., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
