Investigating Loss of Relativistic Electrons Associated With EMIC Waves at Low L Values on 22 June 2015

Journal of Geophysical Research - Space Physics, 2019
In this study, rapid loss of relativistic radiation belt electrons at low L* values (2.4–3.2) during a strong geomagnetic storm on 22 June 2015 is investigated along with five possible loss mechanisms.

Relativistic Microburst Scale Size Induced by a Single Point‐Source Chorus Element

Geophysical Research Letters, 2022
Relativistic microbursts are impulsive, sub‐second precipitation bursts of relativistic electrons. They are one of the main loss mechanisms of outer radiation belt electrons, and are driven by chorus waves.

Scattering of Ultra-relativistic Electrons in the Van Allen Radiation Belts Accounting for Hot Plasma Effects

Scientific Reports, 2017
Electron flux in the Earth’s outer radiation belt is highly variable due to a delicate balance between competing acceleration and loss processes. It has been long recognized that Electromagnetic Ion Cyclotron (EMIC) waves may play a crucial role in the ...

Relativistic Electron Microbursts as High‐Energy Tail of Pulsating Aurora Electrons

Geophysical Research Letters, 2020
In this study, by simulating the wave‐particle interactions, we show that subrelativistic/relativistic electron microbursts form the high‐energy tail of pulsating aurora (PsA).

Local heating of radiation belt electrons to ultra-relativistic energies

Nature Communications, 2020
Electrically charged particles are trapped by the Earth’s magnetic field, forming the Van Allen radiation belts. Observations show that electrons in this region can have energies in excess of 7 MeV.

Relativistic Electrons Produced by Foreshock Disturbances Observed Upstream of Earth's Bow Shock. [PDF]

Physical Review Letters, 2016
Charged particles can be reflected and accelerated by strong (i.e., high Mach number) astrophysical collisionless shock waves, streaming away to form a foreshock region in communication with the shock.

Relativistic Electron Flux Prediction at Geosynchronous Orbit Based on the Neural Network and the Quantile Regression Method

Space Weather, 2020
Geosynchronous satellites are exposed to the relativistic electrons, which may cause irreparable damage to the satellites. The prediction of the relativistic electron flux is therefore important for the safety of the satellites.

Acceleration of sub-relativistic electrons with an evanescent optical wave at a planar interface.

Optics Express, 2017
We report on a theoretical and experimental study of the energy transfer between an optical evanescent wave, propagating in vacuum along the planar boundary of a dielectric material, and a beam of sub-relativistic electrons.
