Hard X-ray sources detected by INTEGRAL and implications for GLAST

Here, we consider the question of which of the 20-100 keV INTEGRAL sources may be detected by GLAST. There are clearly some source types that the two satellites will have in common, such as Active Galactic Nuclei, rotation-powered pulsars, and supernova remnants, but we have performed a detailed cross-correlation between the positions of the 499 INTEGRAL sources and the 271 EGRET sources that were detected at > 100 MeV We find that 31 of the EGRET sources have at least one INTEGRAL source in their error circle. Although source confusion is a problem in the Galactic Center region, we find 4 possible associations between EGRET sources and High-Mass X-ray Binaries in the Galactic disk. This could indicate that some fraction of HMXB's will be seen by GLAST.
