Search for Galactic neutron sources with the Pierre Auger Observatory: correlations with x-ray binaries and supernova remnants

In this study the results are reported of searches, using data from the surface detector of the Pierre Auger Observatory, for potential Galactic neutron sources near objects in three catalogs: low mass x-ray binaries, high mass x-ray binaries, and supernova remnants. The search was performed in windows of $1^\circ$ increments from $1^\circ$ to $10^\circ$ around catalog objects in six energy ranges. The maximum excess found was $3.5 \sigma$ in the energy range 1.5 -- 2.5 EeV in a $3^\circ$ window around high mass x-ray binaries. The chance probability of finding an excess this large in this search is estimated to be 1\%.
