A Search for Millimeter-bright Blazars as Astrophysical Neutrino Sources

open access: yesThe Astrophysical Journal
The powerful jets of blazars have been historically considered as likely sites of high-energy cosmic-ray acceleration. However, the particulars of the launched jet and the locations of leptonic and hadronic jet loading remain unclear.

VLBI Analysis of a Potential High-Energy Neutrino Emitter Blazar

open access: yesUniverse
Recent studies suggest that high-energy neutrinos can be produced in the jets of blazars, radio-loud active galactic nuclei (AGN) with jets pointing close to the line of sight.
