Wave and particle measurements for chorus emissions by GEOTAIL in the magnetosphere
Satoshi Yagitani,Isamu Nagano,Hiroshi Matsumoto,Yoshiharu Omura,William R. Paterson,L. A. Frank,Roger R. Anderson +6 more
TL;DR: In this article, a comparison between wave and particle data for chorus emissions in the dayside outer magnetosphere is performed using the GEOTAIL spacecraft for chorus measurements, showing that the measured profiles of cyclotron resonant electrons are likely to represent distribution functions after the pitch angle diffusion by the simultaneously observed chorus emissions, rather than those responsible for generating the emissions.

TL;DR: In this paper, the late time coupling of the ionized cloud with the collisionless ambient plasma in the magnetosphere is investigated for each of the releases, qualitatively consistent with predictions from theory in that the coupling time increases with increasing distance from the Earth.

Relationship between X-Ray, ultraviolet, and kilometric radiation in the auroral region
W. L. Imhof,M. Walt,Roger R. Anderson,J. D. Hawley,Mitchell J. Brittnacher,S. M. Petrinec,Hiroshi Matsumoto +6 more
TL;DR: In this paper, the simultaneous emission of X-ray and UV photons as a function of time and location in the auroral oval, and comparisons are made of their time variations with the intensity variations of Auroral Kilometric Radiation (AKR).

The dependence of AKR production on the intensity and energy spectra of auroral bremsstrahlung
W. L. Imhof,Roger R. Anderson,M. Walt,J. D. Hawley,S. M. Petrinec,J. Mobilia,Hiroshi Matsumoto +6 more
TL;DR: In this paper, the energy dependence of electron precipitation associated with auroral kilometric radiation (AKR) production is improved with the use of bremsstrahlung x-ray measurements.
