Acceleration of Charged Particles in Astrophysical Plasmas
Frontiers in Astronomy and Space Sciences, 2021 The origin of high-energy particles in the Universe is one of the key issues of high-energy solar physics, space science, astrophysics, and particle astrophysics.

Radio Pulsars Resonantly Accelerating Electrons
Astronomy, 2023 Based on the recently demonstrated resonant wave–wave process, it is shown that electrons can be accelerated to ultra-relativistic energies in the magnetospheres of radio pulsars. The energization occurs via the resonant interaction of the electron wave (

Clustering of fast gyrotactic particles in low-Reynolds-number flow.
PLoS ONE, 2022 Systems of particles in turbulent flows exhibit clustering where particles form patches in certain regions of space. Previous studies have shown that motile particles accumulate inside the vortices and in downwelling regions, while light and heavy non ...

Fine Structure of Solar Metric Radio Bursts: ARTEMIS-IV/JLS and NRH Observations
Universe, 2023 Radio bursts provide important diagnostics of energetic phenomena of the Sun. In particular, bursts in decimetric and metric wavelengths probe the physical conditions and the energy release processes in the low corona as well as their association with ...

Neutral particle acceleration by spatially modulated laser pulses
New Journal of Physics, 2023 The velocity gain of neutral particles (atoms, molecules, etc) from laser acceleration is always small. A possible scheme to obtain a high speed neutral particle beam is multistage acceleration. However, according to previous theoretical and experimental

Particle Acceleration in Relativistic Outflows [PDF]
Space Science Reviews, 2012 In this review we confront the current theoretical understanding of particle acceleration at relativistic outflows with recent observational results on various source classes thought to involve such outflows, e.g. gamma-ray bursts, active galactic nuclei, and pulsar wind nebulae.

Kinetic energy partitions in electron–ion PIC simulations of ABC fields
Nukleonika, 2023 We explore the kinetic energy partitions between electrons and ions in the 2-D magnetostatic equilibria called Arnold–Beltrami–Childress (ABC) fields, using particle-in-cell (PIC) numerical simulations.

A Novel Mechanism of Pair Creation in Pulsar Magnetospheres
Universe, 2021 In this paper we study the possibility of efficient pair production in a pulsar’s magnetosphere. It has been shown that by means of relativistic centrifugal force the electrostatic field exponentially amplifies.
