Implication

Calculations reveal boosted neutrino flux from cosmic-ray and supernova interactions, suggesting detection potential in Active Galactic Nuclei.

Key Points

  • A detectable flux of high-energy neutrinos could arise from cosmic-ray scattering with supernova neutrinos.
  • Under specific astrophysical conditions, neutrinos with energies of 10-100 TeV could enhance detection by neutrino telescopes.
  • The proposed mechanism suggests new constraints on the ultra-high energy proton-neutrino cross section.
  • Increased cross section due to extra-dimensional theories supports potential observations of boosted neutrino signals.
