Search for Correlations of High-energy Neutrinos Detected in IceCube with Radio-bright AGN and Gamma-Ray Emission from Blazars

Abstract The IceCube Neutrino Observatory sends realtime neutrino alerts with a high probability of being astrophysical in origin. We present new method to correlate these events and possible candidate sources using 2089 blazars from the Fermi-LAT 4LAC-DR2 catalog 3413 active galactic nuclei (AGNs) Radio Fundamental Catalog. No statistically significant emission was found any searches. result suggests that small fraction, <1%, studied AGNs emit neutrinos pass alert criteria, is compatible prior evidence for presented by other authors such as TXS 0506 + 056 PKS 1502 106. also cross-checks analyses claim correlation similar data samples.
