TL;DR: In this paper, a computer simulation of the wave-particle interactions between the lower-band chorus (LBC) waves and electrons was conducted to show that scattering by propagating whistler simultaneously causes both the precipitations of sub-relativistic electrons and the pulsating aurora.

TL;DR: In this article, the authors introduce the specifications of the Plasma Wave Experiment (PWE) on board the Arase satellite, which consists of an orthogonal electric field sensor (WPT; wire probe antenna), a triaxial magnetic sensor (MSC; magnetic search coil), and receivers named electric field detector (EFD), waveform capture and onboard frequency analyzer (WFC/OFA), and high-frequency analyzer(HFA), was developed to measure the DC electric field and plasma waves in the inner magnetosphere.

TL;DR: The High Frequency Analyzer (HFA) is a subsystem of the Plasma Wave Experiment onboard the Arase (ERG) spacecraft as mentioned in this paper, which is used for determining the electron number density around the spacecraft from observations of upper hybrid resonance (UHR) waves, measuring the electromagnetic field component of whistler-mode chorus in a frequency range above 20 kHz, and observing radio and plasma waves excited in the storm-time magnetosphere.

TL;DR: Sub-second scintillations of aurorae are precisely controlled by fine-scale chirping rhythms in chorus, demonstrating that resonant interaction between energetic electrons and chorus waves in magnetospheres orchestrates the complex behavior of aurora on Earth and other magnetized planets.

TL;DR: The PWING project as mentioned in this paper has been carried out since April 2016 to provide the global distribution and quantitative evaluation of the dynamical variation of these plasmas and waves in the inner magnetosphere.
