Growing evidence for high-energy neutrinos originating in radio blazars by A. V. Plavin et al. on Monday 21 November
Evidence for bright radio blazars being high-energy neutrino sources was
found in recent years. Specifics of how and where these particles get produced
still remain not fully determined. In this paper, we add 14 new IceCube
detections from 2020-2022 to update our analysis of the neutrino-blazars
connection. We test and refine earlier findings by utilizing the total of 71
track-like high-energy IceCube events from 2009-2022. We correlate them with
the complete sample of 3412 extragalactic radio sources selected by their
compact radio emission. We demonstrate that neutrinos are statistically
associated with radio-bright blazars with the post-trial p-value of 3*10^-4. In
addition to this statistical study, we confirm previous individual
neutrino-blazar associations, find and discuss several new ones. Notably, PKS
1741-038 was selected earlier and had the second neutrino detected from its
direction in 2022; PKS 0735+168 has experienced a major flare across the whole
electromagnetic spectrum coincidently with a neutrino arrival from that
direction in 2021.
