Effective fermion mass in relativistic and non-relativistic systems
New Journal of Physics, 2021 Electrons interact strongly with their environment. The result of these interactions is, most of the time, encoded in an effective mass. In non-relativistic systems, as in condensed matter, the electrons plus interactions form a quasiparticle with an ...

PreMevE Update: Forecasting Ultra‐Relativistic Electrons Inside Earth's Outer Radiation Belt
Space Weather, 2021 Energetic electrons inside Earth's Van Allen belts pose a major radiation threat to space‐borne electronics that often play vital roles in modern society. Ultra‐relativistic electrons with energies greater than or equal to two megaelectron‐volt (MeV) are

Simultaneous Precipitation of Sub‐Relativistic Electron Microburst and Pulsating Aurora Electrons
Geophysical Research Letters, 2023 We have identified for the first time an energy‐time dispersion of precipitating electron flux in a pulsating aurora patch, ranging from 6.7 to 580 keV, through simultaneous in‐situ observations of sub‐relativistic electrons of microburst precipitations ...

Frontiers in Astronomy and Space Sciences, 2021 When the Earth’s moon is in the supersonic solar wind, the darkside of the Moon and the lunar plasma wake can be very dangerous charging environments. In the absence of photoelectron emission (dark) and in the absence of cool plasma (wake), the emission ...

Pitch Angle Scattering of Sub‐MeV Relativistic Electrons by Electromagnetic Ion Cyclotron Waves
Journal of Geophysical Research: Space Physics, 2019 Electromagnetic ion cyclotron (EMIC) waves have long been considered to be a significant loss mechanism for relativistic electrons. This has most often been attributed to resonant interactions with the highest amplitude waves.

Interferometry with relativistic electrons [PDF]
Physical Review A, 2014 We propose an experiment to test the influence of Lorentz contraction on the interference pattern of a beam of electrons. The electron beam is split and recombined by two pairs of bi-chromatic laser pulses, using a variation of the Kapitza-Dirac effect. Between the pairs the electrons are accelerated to relativistic speed.

Simulating the Enrichment of Fossil Radio Electrons by Multiple Radio Galaxies
Galaxies, 2023 We simulate the evolution of relativistic electrons injected into the intracluster medium by five radio galaxies. We study the spatial transport and the emission properties of the injected radio plasma over a ∼5 Gyr period, and the sequence of cooling ...

Relativistic electrons generated at Earth’s quasi-parallel bow shock
Science Advances, 2019 Nonlinear structures can increase electron acceleration efficiency at quasi-parallel shocks by an order of magnitude. Plasma shocks are the primary means of accelerating electrons in planetary and astrophysical settings throughout the universe.

EXPANSION OF COCOONS AND PHYSICAL FEATURES OF THE FRI-FRII MORPHOLOGY OF EXTRAGALACTIC RADIO SOURCES
Odessa Astronomical Publications, 2007 It is shown that the morphological different FRI-FRII structures arise in depending on the type of interaction of the relativistic electrons with MHD cocoon turbulence, on velocity of turbulence dissipation, and on the power of extragalactic radio ...
