TeV Gamma-Rays from the Low-Luminosity Active Galactic Nucleus NGC 4278: Implications for the Diffuse Neutrino Background

Chengchao Yuan, Ruo-Yu Liu

Lepto-hadronic winds in low-luminosity AGN can explain the PeV diffuse neutrino background once the local density is corrected for a TeV duty cycle of order 10^{-5}.

Claims

C1strongest claim

a lepto-hadronic wind scenario can account for the PeV diffuse neutrino background when adopting a local LLAGN density (n_L,0) corrected for the TeV duty cycle (ΔT_TeV/T) ~ 10^{-5} Mpc^{-3}, as inferred from the LHAASO detection.

C2weakest assumption

That the observed TeV emission is produced by lepto-hadronic processes in sub-relativistic winds rather than leptonic jets, and that the single-source LHAASO detection can be used to infer a population-wide duty-cycle-corrected density that directly scales to the diffuse neutrino background.

C3one line summary

Lepto-hadronic winds in LLAGNs like NGC 4278 can account for the PeV diffuse neutrino background with a duty-cycle-corrected local density of ~10^{-5} Mpc^{-3} inferred from LHAASO data.
