An Hourly Prediction Model of Relativistic Electrons Based on Empirical Mode Decomposition

Space Weather, 2020
During the recovery of a magnetic storm, the relativistic electrons at megaelectron volt energy from the outer radiation belt will be enhanced at the geosynchronous orbit.

On the Effect of Geomagnetic Storms on Relativistic Electrons in the Outer Radiation Belt: Van Allen Probes Observations

Journal of Geophysical Research: Space Physics, 2017
Using Van Allen Probes Energetic Particle, Composition, and Thermal Plasma‐Relativistic Electron‐Proton Telescope (ECT‐REPT) observations, we performed a statistical study on the effect of geomagnetic storms on relativistic electrons fluxes in the outer ...

Prompt energization of relativistic and highly relativistic electrons during a substorm interval: Van Allen Probes observations

Geophysical Research Letters, 2014
On 17 March 2013, a large magnetic storm significantly depleted the multi‐MeV radiation belt. We present multi‐instrument observations from the Van Allen Probes spacecraft Radiation Belt Storm Probe A and Radiation Belt Storm Probe B at ~6 Re in the ...

Nonresonant Scattering of Relativistic Electrons by Electromagnetic Ion Cyclotron Waves in Earth's Radiation Belts. [PDF]

Physical Review Letters, 2022
Electromagnetic ion cyclotron waves are expected to pitch-angle scatter and cause atmospheric precipitation of relativistic (>1  MeV) electrons under typical conditions in Earth's radiation belts.

Galaxy clusters enveloped by vast volumes of relativistic electrons [PDF]

Nature, 2022
The central regions of galaxy clusters are permeated by magnetic fields and filled with relativistic electrons1. When clusters merge, the magnetic fields are amplified and relativistic electrons are re-accelerated by turbulence in the intracluster ...

Measurement of magnetic field and relativistic electrons along a solar flare current sheet [PDF]

Nature Astronomy, 2020
In the standard model of solar flares, a large-scale reconnection current sheet is postulated to be the central engine for powering the flare energy release1–3 and accelerating particles4–6.

Testing the key processes that accelerate outer radiation belt relativistic electrons during geomagnetic storms

Frontiers in Astronomy and Space Sciences, 2023
Since the discovery of the Earth’s radiation belts in 1958, it has always been a challenge to determine the dominant physical mechanisms, whether local acceleration by chorus or inward radial diffusion, that leads to outer radiation belt relativistic ...

A New Population of Ultra‐Relativistic Electrons in the Outer Radiation Zone

Journal of Geophysical Research - Space Physics, 2022
Van Allen Probes measurements revealed the presence of the most unusual structures in the ultra‐relativistic radiation belts. Detailed modeling, analysis of pitch angle distributions, analysis of the difference between relativistic and ultra‐realistic ...

Resonant enhancement of relativistic electron fluxes during geomagnetically active periods [PDF]

Annales Geophysicae, 1999
The strong increase in the flux of relativistic electrons during the recovery phase of magnetic storms and during other active periods is investigated with the help of Hamiltonian formalism and simulations of test electrons which interact with ...
