Geophysical Monograph Series, Page 1-26., 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.

Radial Transport in the Earth’s Radiation Belts: Linear, Quasi-linear, and Higher-order Processes
The Astrophysical Journal Supplement Series, 2023 Observational studies of the Earth’s radiation belts indicate that Alfvénic fluctuations in the frequency range of 2–25 mHz accelerate electrons to relativistic energies.

Differentiating Between the Leading Processes for Electron Radiation Belt Acceleration
Frontiers in Astronomy and Space Sciences, 2022 Many spacecraft fly within or through a natural and variable particle accelerator powered by the coupling between the magnetosphere and the solar wind: the Earth’s radiation belts.

A radiation hardened digital fluxgate magnetometer for space applications [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2013 Space-based measurements of Earth's magnetic field are required to understand the plasma processes responsible for energising particles in the Van Allen radiation belts and influencing space weather. This paper describes a prototype fluxgate magnetometer

Impulse-driven oscillations of the near-Earth's magnetosphere [PDF]
Annales Geophysicae, 2022 It is argued that a simple model based on magnetic image arguments suffices to give a convincing insight into both the basic static as well as some transient dynamic properties of the near-Earth's magnetosphere, particularly accounting for damped ...

Radial dependence of ionization losses of protons of the Earth's radiation belts [PDF]
Annales Geophysicae, 2016 Coulomb losses and charge exchange of protons are considered in detail. On the basis of modern models of the plasmasphere and the exosphere, the radial dependences of the rates of ionization losses of protons, with μ from 0.3 to 10 keV nT−1, of the ...

Space Weather, 2021 The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field.

Satellite observations of lightning-induced hard X-ray flux enhancements in the conjugate region [PDF]
Annales Geophysicae, 2006 Preliminary examination of October-December 2002 SONG (SOlar Neutron and Gamma rays) data aboard the Russian CORONAS-F (Complex Orbital Near-Earth Observations of the Activity of the Sun) low-altitude satellite has revealed many X-ray enhanced ...

Wave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts
Nature Communications, 2016 The processes that lead to losses of highly energetic particles from Earth’s radiation belts remain poorly understood. Here the authors compare observations and models of a 2013 event to show that electromagnetic ioncyclotron waves provide the dominant ...

Chorus wave-normal statistics in the Earth's radiation belts from ray tracing technique [PDF]
Annales Geophysicae, 2012 Discrete ELF/VLF (Extremely Low Frequency/Very Low Frequency) chorus emissions are one of the most intense electromagnetic plasma waves observed in radiation belts and in the outer terrestrial magnetosphere.
