  The IceCube Neutrino Observatory has provided the first map of the high
energy (~ 0.01 -- 1 PeV) sky in neutrinos. Since neutrinos propagate
undeflected, their arrival direction is an important identifier for sources of
high energy particle acceleration. Reconstructed arrival directions are
consistent with an extragalactic origin, with possibly a galactic component, of
the neutrino flux. We present a statistical analysis of positional coincidences
of the IceCube neutrinos with known astrophysical objects from several
catalogs. When considering starburst galaxies with the highest flux in
gamma-rays and infrared radiation, up to n=8 coincidences are found,
representing an excess over the ~4 predicted for the randomized, or "null"
distribution. The probability that this excess is realized in the null case,
the p-value, is p=0.042. This value falls to p=0.003 for a partial subset of
gamma-ray-detected starburst galaxies and superbubble regions in the galactic
neighborhood. Therefore, it is possible that starburst galaxies, and the
typically hundreds of superbubble regions within them, might account for a
portion of IceCube neutrinos. The physical plausibility of such correlation is
discussed briefly.
