Four Solar Orbiter interplanetary shocks show energetic particle pressure dominating upstream, indicating particle-mediated modification of collisionless shocks.
A self-consistent multi-zone kinetic model reproduces SN 1006's spectrum and morphology, finding ~20% CR acceleration efficiency in quasi-parallel shocks, <1% in quasi-perpendicular shocks, and predominantly leptonic gamma-ray emission.
Derives and validates via PIC simulations a scaling law for nonthermal spectral tails in mildly to strongly magnetized turbulent plasmas, with application to black-hole coronae.
A toy model of reverse shocks in novae predicts GeV gamma rays near optical peak and potential TeV emission later, consistent with Fermi observations under an empirically thin post-shock layer.
Coherent structures that self-consistently emerge in strong MHD turbulence serve as the dominant sites for localized electric-field intensification and repeated particle acceleration across cosmic plasmas.
This review summarizes the basic principles of electron transport in inhomogeneous and tangled magnetic fields through gyro-centre trajectories, kinetic instabilities, trapping, and diffusion processes.
