  Searches for spatial associations between high-energy neutrinos observed at
the IceCube Neutrino Observatory and known astronomical objects may hold the
key to establishing the neutrinos' origins and the origins of hadronic cosmic
rays. While extragalactic sources like the blazar TXS 0506+056 merit
significant attention, Galactic sources may also represent part of the puzzle.
Here, we explore whether open clusters and supernova remnants in the Milky Way
contribute measurably to the IceCube track-like neutrino events above 200 TeV.
By searching for positional coincidences with catalogs of known astronomical
objects, we can identify and investigate neutrino events whose origins are
potentially Galactic. We use Monte Carlo randomization together with models of
the Galactic plane in order to determine whether these coincidences are more
likely to be causal associations or random chance. In all analyses presented,
the number of coincidences detected was found to be consistent with the null
hypothesis of chance coincidence. Our results imply that the combined
contribution of Galactic open clusters and supernova remnants to the track-like
neutrino events detected at IceCube is well under 30%. This upper limit is
compatible with the results presented in other Galactic neutrino studies.
