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.

Radio Emission from Ultra-Cool Dwarfs

TL;DR: In this paper, radio emission from ultra-cool dwarfs (UCDs), the very low-mass stars and brown dwarfs with spectral types of ~M7 and later, revealed that these objects can generate and dissipate powerful magnetic fields.

Extinct radio pulsars as a source of subrelativistic positrons

TL;DR: In this article, the authors assume that the observed excess of positrons in the bulge and the disc of the Galaxy is associated with these old neutron stars, and they estimate the total flux of positron from all old Galactic neutron stars with rotational periods $1.5 < P < 35$ s.

Locating the source field lines of Jovian decametric radio emissions

TL;DR: In this article, the authors proposed a method to locate the source region as well as the associated field lines for any given DAM emission recorded in a radio dynamic spectrum by, e.g., wind/waves or STEREO/WAVES.

A multi-instrument study of auroral hiss at Saturn

TL;DR: The first comprehensive study of auroral hiss at a planet other than Earth, using the Cassini spacecraft to study the low frequency whistler-mode wave that is produced in the auroral zone, was presented in this paper.

Kinetic simulation of the electron-cyclotron maser instability: effect of a finite source size

TL;DR: In this article, a kinetic code was developed to simulate the time evolution of an electron distribution in a radio emission source, including the terms describing the particle injection to and escape from the emission source region.
