An upper limit on the high-energy gamma-ray emission of VELA X-1.

Kanbach, G.; Oegelman, H.; Mattox, J. R.

The possibility of high-energy gamma-ray emission from the X-ray binary Vela X-1 was investigated by analyzing the COS-B satellite observations, using the COS-B X-ray detector for a phase coherent analysis in the search of rotational periodicity. The rotational upper limit is compared to the X-ray, TeV, and PeV fluxes reported by Chodil et al. (19…
