Discovery of the Earth's Van Allen radiation belts by instruments flown on Explorer 1 in 1958
was the first major discovery of the Space Age. The observation of distinct inner and outer …

One of the most important issues in space physics is to identify the dominant processes that
transfer energy from the solar wind to energetic particle populations in Earth's inner …

Dayside transients, such as hot flow anomalies, foreshock bubbles, magnetosheath jets, flux
transfer events, and surface waves, are frequently observed upstream from the bow shock …

We present NASA Van Allen Probes observations of wave‐particle interactions between
magnetospheric ultra‐low frequency (ULF) waves and energetic electrons (20–500 keV) on …

Using our recently introduced hybrid finite difference method, we develop a three‐
dimensional (3‐D) code to solve a fully bounce‐averaged pitch‐angle and energy diffusion …

Interplanetary discontinuities and their geomagnetic effects are reviewed for
magnetospheric/space weather researchers. Discontinuities are particularly useful as …

Ultra‐low frequency waves interact with different particle populations all over the
magnetosphere. Some interaction mechanisms are associated with certain wave modes, but …

The impact of radial diffusion in storm time radiation belt dynamics is well‐debated. In this
study we quantify the changes and variability in radial diffusion coefficients during …

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 …

Abstract Ultra‐low‐frequency (ULF) waves are known to radially diffuse hundreds‐keV to
few‐MeV electrons in the magnetosphere, as the range of drift frequencies of such electrons …
