TLDR
In this paper, it was found that reflected electrons can result in the amplification of electromagnetic waves via a relativistic normal cyclotron resonance, which may explain the recently discovered terrestrial kilometric radiation.Abstract:
During magnetospheric substorms, electrons with energies of about 1 keV are injected from the plasma-sheet region into the auroral region. A fraction of these energetic electrons can precipitate into the upper atmosphere, and the rest are reflected because of the mirror effect of the convergent geomagnetic field. It is found that these reflected electrons can result in the amplification of electromagnetic waves via a relativistic normal cyclotron resonance. This process may explain the recently discovered terrestrial kilometric radiation.read more

Radio noise of auroral origin: 1968–1988
TL;DR: There have been various reports of radio noise from the aurora dating back to 1946 as discussed by the authors, and a previous review appeared in 1969 and covered the period 1946-1967; in this review we concentrate on the observations between 1968 and 1988.

Production of auroral kilometric radiation by gyrophase-bunched double-layer-emitted electrons: antennae in the magnetospheric current regions
TL;DR: In this article, the gyrophase-bunched sheet beams of electrons that emanate from magnetized double layers may produce electromagnetic radiation with high efficiencies in narrow frequency bands.

Field-independent source localization of Neptune's radio bursts
TL;DR: In this paper, a narrowbanded bursty radio component was observed between 500 and 1326 kHz by the Planetary Radio Astronomy instrument, and the radio source was localized without the explicit use of the Neptunian offset-tilted dipole magnetic field model, which is accurate only at distances greater than 4 R(N) (Neptune radii) from the planet.

The source location of certain Jovian decametric radio emissions
TL;DR: In this article, it was determined that the wave signals received by Voyager 1 near 10 MHz shortly after the closest approach to Jupiter were found to exhibit cusps in the fringe pattern which can be attributed to Faraday rotation in the Io plasma torus.
