Perturbative analysis of the breathing circle billiard map combined with a quantitative Mather converse-KAM criterion excludes invariant Lipschitz graphs and establishes positive topological entropy for sufficiently small angular momentum.
In magnetically dominated relativistic collisionless plasmas, Alfvén and slow modes follow anisotropic Goldreich-Sridhar scaling, fast modes are isotropic with larger kinetic energy fraction, and dynamic alignment weakens near kinetic scales due to thermal fluctuations.
Advection-only galactic wind models fail to reproduce observed vertical radio profiles without unrealistic velocities, synchrotron spectra are biased toward young electrons in dense regions, and bremsstrahlung/Coulomb losses cannot be neglected even when subdominant.
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.
Reconnection injects suprathermal protons during cosmological magnetogenesis yielding a ~10^{-7} nonthermal energy fraction that provides only a minor seed for later shock acceleration.
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.
Oblique shocks in massive star clusters accelerate cosmic rays to multi-PeV energies, reproducing the LHAASO-observed knee as a sequence of rigidity-dependent cutoffs from combined supernova and wind shocks.
Numerical MHD and test-particle simulations indicate that unsteady loop-top dynamics enhance electron acceleration efficiency compared to quasi-steady cases by mitigating betatron cooling at compressed field edges.
LAMBDA proposes megameter-scale baselines using additional Australian stations to extend SKA-Low for high-resolution low-frequency VLBI.
PIC-motivated acceleration models for GRB afterglows predict a GeV-band synchrotron cutoff in low-density short GRBs that current Fermi-LAT data cannot distinguish from the Bohm limit but future observations could.
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.
Review summarizing observational data on the Milky Way's magnetic field structure, including spiral alignment, halo components, turbulence, and correlations with interstellar gas and dust.
Review assessing HSP BL Lacs as UHECR and neutrino sources, noting strains from baryonic loading, heavy-nuclei preference in Auger data, and isotropy mismatch with beamed sources.
