Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic (∼∼ few
GeV) energies are accelerated near the Sun in at least two ways:(1) by magnetic …

Particles are accelerated to very high, non-thermal energies during explosive energy-
release phenomena in space, solar, and astrophysical plasma environments. While it has …

A nonthermal particle acceleration mechanism involving the interaction of a charged particle
with multiple magnetic islands is proposed. The original Fermi acceleration model, which …

Shock waves propagating in collisionless heliospheric and astrophysical plasmas have
been studied extensively over the decades. One prime motivation is to understand the …

Particles are accelerated to very high, non-thermal energies in solar and space plasma
environments. While energy spectra of accelerated electrons often exhibit a power law, it …

Motivated by the presentations and discussions carried out at the Magnetic Reconnection
Workshop, held at the National Institute for Space Research (INPE) of Brazil in March 2014 …

Abstract We perform a 2.5-dimensional particle-in-cell simulation of a quasi-parallel shock,
using parameters for the Earth's bow shock, to examine electron acceleration and heating …

We present one case study of magnetic islands and energetic electrons in the reconnection
diffusion region observed by the Cluster spacecraft. The cores of the islands are …

Solar flares produce non-thermal electrons with energies up to tens of MeVs. To understand
the origin of energetic electrons, coronal hard X-ray (HXR) sources, in particular above-the …

Fully kinetic two-dimensional particle-in-cell simulations are used to study electron
acceleration at high-Mach-number nonrelativistic perpendicular shocks. Supernova remnant …
