We consider the acceleration of energetic particles by Fermi processes (i.e., diffusive shock acceleration, second order Fermi acceleration, and gradual shear acceleration) in relativistic astrophysical jets, with particular attention given to recent progress in the field of viscous shear acceleration. We analyze the associated acceleration timescales and the resulting particle distributions, and discuss the relevance of these processes for the acceleration of charged particles in the jets of AGNs, GRBs and microquasars, showing that multi-component powerlaw-type particle distributions are likely to occur.

  1. Magnetic rigidity reveals the PeVatron acceleration region in SS433

    astro-ph.HE 2026-08 conditional novelty 6.0 of 10

    The radio-measured magnetic field in SS 433's inner jet declines as H^-0.5, so the jet retains enough magnetic rigidity at ~100 AU to accelerate protons to PeV energies.

  2. Multi-wavelength analysis of FSRQ B2 1348+30B: Constraints on the jet power

    astro-ph.HE 2025-06 reject novelty 5.0 of 10

    A 14.5-year multiwavelength analysis of the blazar B2 1348+30B yields jet power limits of about 2.6e46 to 4.2e48 erg/s, with the heavy-jet estimate far exceeding Eddington luminosity.

  3. SKAO and Gamma-Ray Synergies

    astro-ph.HE 2026-06 unverdicted novelty 2.0 of 10

    Overview of synergies between SKA radio observations and gamma-ray facilities for studying transient, variable, and steady GeV-TeV sources.
