Abstract
We find a statistically significant correlation between the positions of unidentified EGRET sources near the Galactic plane and OB associations. Nine of the unidentified EGRET sources have position contours overlapping an OB association, and an additional seven lie within 1° of an OB association. Using the known OB association distances to determine the intrinsic luminosity of the gamma-ray sources, we find a distribution of luminosities consistent with that of known gamma-ray pulsars. These results are consistent with the interpretation that young pulsars constitute the majority of the unidentified gamma-ray point sources near the Galactic plane.
