A Flux Rope Network and Particle Acceleration in Three Dimensional Relativistic Magnetic Reconnection
TL;DR: In this paper, the authors investigate guide-field magnetic reconnection and particle acceleration in relativistic pair plasmas with three-dimensional particle-in-cell simulations of a kinetic-scale current sheet in a periodic geometry at low magnetizations.
Journal ArticleDOI
Slow diffusion of cosmic rays around a supernova remnant
TL;DR: In this paper, the escape of cosmic-ray protons accelerated at a supernova remnant (SNR) was studied using Monte Carlo simulations, and it was shown that the cosmic rays with energies of TeV excite Alfven waves around the SNR on a scale of SNR itself if the ISM is highly ionized.

First-Order Particle Acceleration in Magnetically-driven Flows
Andrey Beresnyak,Hui Li +1 more
TL;DR: In this paper, the authors demonstrate that particles are regularly accelerated while experiencing curvature drift in flows driven by magnetic tension, where a magnetic field relaxes to a lower energy configuration and transfers part of its energy to kinetic motions of the fluid.

Composition of cosmic rays at ultra high energies
TL;DR: In this article, measurements of the cosmic ray (CR) composition above 10 15 eV, performed with the Yakutsk extensive air shower array, were performed for the analysis of the depth of maximum of the longitudinal development of air showers induced by CRs.

TL;DR: The Fermi Large Area Telescope has recently discovered two giant gamma-ray bubbles that extend north and south of the Galactic center with diameters and heights of the order of H {approx} 10 kpc as discussed by the authors.
