TL;DR: In this paper, the authors report observations of fast solitary waves that are ubiquitous in downward current regions of the mid-altitude auroral zone and propose that these nonlinear structures play a key role in supporting parallel electric fields.

TL;DR: In this article, the acceleration of upgoing electron beams by quasi-static parallel electric fields was detected in the winter auroral zone, and the most energetic ion conics were found coincident with these beams, in agreement with the model for trapped conics.

TL;DR: In this article, the authors demonstrate that parallel electric fields may be a fundamental particle acceleration mechanism in astrophysical plasmas by comparing the inferred parallel potentials of electrostatic shocks with particle energies.

TL;DR: In this article, a large amplitude impulsive electric and magnetic field oscillations are observed from FAST when crossing the dayside auroral oval at altitudes from 1500-2500 km.

TL;DR: The Fast Auroral SnapshoT (FAST) satellite has made observations in the Auroral Kilometric Radiation (AKR) source region with unprecedented frequency and time resolution as mentioned in this paper.
