Gamma-Ray Imaging Observations of Point Source Emission From the Galactic Center Region
Abstract
The first coded-aperture images of the galactic center region at energies above 30 keV reveal two strong 7-ray sources. One source is tentatively identified as the X-ray source 1El740.7-2942. If this source is at the distance of the galactic center, it is one of the most luminous objects in the galaxy at energies from 35 to 200 keV. The second source is consistent in location with the X-ray source GX354-0. No significant flux was detected from the direction of the galactic nucleus (Sgr A*).
