Abstract (from CDS):

We present a catalog of 2-10 keV ASCA Gas Imaging Spectrometer images of fields containing bright sources of GeV emission. The images cover ∼85% of the 95% confidence position contour for 28 of the 30 sources with >1 GeV fluxes above 4x10–8 ph.cm–2.s–1. We find an excess of hard X-ray sources with F2–10keV≳10–12 ergs.cm–2.s–1 positionally coincident with unidentified sources of GeV emission. We comment on radio-loud and radio-quiet pulsar candidates, as well as several SNRs and massive binaries as possible sources of the GeV emission. We also find evidence for a class of variable γ-ray sources associated with extended regions of hard X-ray emission, and propose that for these sources, a significant percentage of the γ-ray emission is generated in synchrotron nebulae surrounding fast, young pulsars.
