Limit on high energy neutrino emission from Abell 119 using IceCube 10-year muon track data
Researchers searched for high-energy muon neutrinos from Abell 119 using 10 years of IceCube data to test if this cluster could explain recent GeV gamma-ray detections suggesting a hadronic origin. The search found no statistically significant excess, setting an upper limit on the neutrino flux at 100 TeV. This result is lower than the predicted flux required by the gamma-ray model.
