The past decade transformed our observational understanding of energetic particle
processes in near‐Earth space. An unprecedented suite of observational systems was in …

The Earth's diffuse auroral precipitation provides the major source of energy input into the
nightside upper atmosphere and acts as an essential linkage of the magnetosphere …

The flux of energetic electrons in the Earth's outer radiation belt can vary by several orders of
magnitude over time scales less than a day, in response to changes in properties of the …

Nonlinear processes associated with the generation process of whistler-mode chorus
emissions are summarized. The nonlinear dynamics of energetic electrons interacting with a …

The Exploration of energization and Radiation in Geospace (ERG) project aims to study
acceleration and loss mechanisms of relativistic electrons around the Earth. The Arase …

The Exploration of energization and Radiation in Geospace (ERG) project explores the
acceleration, transport, and loss of relativistic electrons in the radiation belts and the …

The generation process of whistler‐mode chorus emissions is analyzed by both theory and
simulation. Driven by an assumed strong temperature anisotropy of energetic electrons, the …

Gyroresonant wave particle interactions with whistler mode chorus play a fundamental role
in the dynamics of the Earth's radiation belts and inner magnetosphere, affecting both the …

We develop a nonlinear wave growth theory of magnetospheric chorus emissions, taking
into account the spatial inhomogeneity of the static magnetic field and the plasma density …

This chapter reviews fundamental properties and recent advances of diffuse and pulsating
aurora. Diffuse and pulsating aurora often occurs on closed field lines and involves …
