Features of energetic particle radial profiles inferred from geosynchronous responses to solar wind dynamic pressure enhancements [PDF]
Annales Geophysicae, 2009 Determination of the radial profile of phase space density of relativistic electrons at constant adiabatic invariants is crucial for identifying the source for them within the outer radiation belt.

Relativistic particle acceleration in an electron–positron plasma with a relativistic electron beam [PDF]
Physics of Plasmas, 1994 Results from three-dimensional electromagnetic particle simulations of an electron–positron plasma with a relativistic electron beam (γ=2) are presented. As part of the initial conditions, a poloidal magnetic field is specified, consistent with the current carried by the beam electrons.

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

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.

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 ...

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 ...

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 ...

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 ...

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.
