A review of the impact of the cold-ion and cold-electron populations in the Earth's
magnetosphere is presented. The cold populations are defined by total energy less than …

Resonant interactions between electrons and chorus waves are responsible for a wide
range of phenomena in near‐Earth space (eg, diffuse aurora and acceleration of> 1 MeV …

Plasma kinetic theory predicts that sufficiently anisotropic proton distribution will excite
electromagnetic ion cyclotron (EMIC) waves, which in turn relax the proton distribution to a …

The composition of the inner magnetosphere is of great importance for determining the
plasma pressure and thus the currents and magnetic field configuration. In this study, we …

Spacecraft observations often reveal the presence of marginally stable chorus and electron
cyclotron harmonic (ECH) waves across a spatial scale about several Earth radii (RE), which …

Abstract We present Van Allen Probes observations of periodic chorus wave emissions in
the troughs of compressional ultralow frequency (ULF) waves. During this event, the spectral …

Plasmaspheric hiss waves are commonly observed in the inner magnetosphere. These
waves efficiently scatter electrons, facilitating their precipitation into the atmosphere …

Electromagnetic ion cyclotron (EMIC) waves play an important role in relativistic electron
dynamics. In this study, we find a large‐amplitude EMIC wave event induced by the prompt …

The background cold electron density plays an important role in plasma and wave
dynamics. Here, we investigate an event with clear modulation of the particle fluxes and …

Abstract Large‐amplitude (Bw> 1 nT) electromagnetic ion cyclotron (EMIC) waves can
cause the rapid loss of> 1 MeV electrons, greatly impacting radiation belt dynamics. With …
