Filamentary Jets as a Cosmic-Ray ``Zevatron''
Abstract
Strong, anisotropic turbulence reflecting magnetized filaments is considered, to model the diffusive acceleration of particles by shock waves in active galactic nucleus jets. We address that at knot A of the nearby M87 jet, the shock involving the filamentary turbulence can accelerate an iron nucleus to zetta-eV (ZeV; 1021 eV) ranges. A smaller value of the particle diffusion coefficient is found to be essential to achieve a ZeV cosmic-ray accelerator, a ``Zevatron.''
