Abstract
We search for plausible neutrino source candidates within the neutrino error regions. Among the sources located within the neutrino error regions, three active sources are selected for analysis:
4FGL J0501.2–0158, 4FGL J0505.3+0459, and 4FGL J0854.8+2006. The Bayesian block method is used to identify periods of flaring. Blocks showing a photon flux significantly higher than 3 standard deviation above that of their surrounding blocks are classified as flares. Among the three active sources, the source 4FGL J0505.3+0459 is identified as plausible neutrino source candidate. The neutrino event IC220918A is found to be originated from the source 4FGL J0505.3+0459.
