Observations of the spectacular, blazar-like tidal disruption event (TDE) candidates Swift J1644+57 and J2058+05 show that the conditions required for accelerating protons to 10^{20} eV appear to be realized in the outer jet, and possibly in the inner jet as well. Direct and indirect estimates of the rate of jetted-TDEs, and of the energy they inject, are compatible with the observed flux of ultra-high energy cosmic rays (UHECRs) and the abundance of presently contributing sources. Thus TDE-jets can be a major source of UHECRs, even compabile with a pure proton composition.

  1. Neutrinos from stochastic acceleration in black hole environments

    astro-ph.HE 2024-12 conditional novelty 6.0 of 10

    A self-regulated stochastic acceleration model, where fast protons damp the corona's turbulence, reproduces the 30 to 300 TeV proton spectrum inferred from IceCube's NGC 1068 neutrino observations.

  2. Neutrino Emissions from Tidal Disruption Remnants

    astro-ph.HE 2019-08 conditional novelty 5.0 of 10

    Tidal disruption remnants around supermassive black holes can emit TeV-PeV neutrinos from three disk states, with predicted light curves that distinguish magnetically arrested disks from ordinary accretion flows.

  3. Multidisciplinary Science in the Multimessenger Era

    astro-ph.HE 2025-02 unverdicted novelty 3.0 of 10

    A community white paper recommending an NNSA-style end-to-end integration of astrophysics, nuclear, plasma, atomic, and computational sciences to maximize return from time-domain and multimessenger facilities.

  4. Ultra High Energy Cosmic Rays

    astro-ph.HE 2025-05 unverdicted

    A comprehensive review concluding that UHECRs are likely heavy nuclei and that accretion shocks and jets are the most promising sources, with no new experimental results.
