Ultra-High-Energy Cosmic Rays Accelerated by Magnetically Dominated Turbulence
The Astrophysical Journal LettersUltra-high-energy cosmic rays (UHECRs), particles characterized by energies exceeding 10 ^18 eV, are generally believed to be accelerated electromagnetically in high-energy astrophysical sources.

The Theory of Resonant Cosmic Ray–driven Instabilities—Growth and Saturation of Single Modes
The Astrophysical JournalCosmic-ray (CR) feedback is critical for galaxy formation as CRs drive galactic winds, regularize star formation in galaxies, and escape from active galactic nuclei to heat the cooling cores of galaxy clusters.

An Exactly Energy-conserving Electromagnetic Particle-in-cell Method in Curvilinear Coordinates
The Astrophysical Journal Supplement SeriesIn this paper, we introduce and discuss an exactly energy-conserving particle-in-cell method for arbitrary curvilinear coordinates. The flexibility provided by curvilinear coordinates enables the study of plasmas in complex-shaped domains by aligning the

Conditions for Relativistic Magnetic Reconnection under the Presence of Shear Flow and Guide Field
The Astrophysical JournalThe scaling of the relativistic reconnection outflow speed is studied in the presence of both shear flows parallel to the reconnecting magnetic fields and guide fields pointing out of the reconnection plane.
