| contents | We search for a spatial association between radio pulsars and ultra-high energy neutrinos using the publicly available IceCube point source neutrino events catalog. For this purpose we use the unbinned maximum likelihood method to search for a statistically significant excess from each of the pulsars in the ATNF catalog. We do not find any pulsars with detection significance much higher than that expected from a Gaussian distribution, Therefore, we conclude that none of the currently known pulsars contribute to the diffuse neutrino flux detected by IceCube. |
