A stacked search for spatial coincidences between IceCube neutrinos and radio pulsars

Abstract

We carry out a stacked search for spatial coincidences between all the known radio pulsars and TeV neutrinos from the IceCube 10 year (2008-2018) muon track data, as a followup to our previous work on searching for spatial coincidences with individual pulsars. We consider three different weighting schemes to stack the contributions from each pulsar. We do not find a statistically significant excess using this method. We report the 95\% c.l. neutrino flux upper limit as a function of the neutrino energy. We have also made our analysis codes publicly available.
