Coded-aperture imaging of the Galactic center region at gamma-ray energies

摘要: The first coded-aperture images of the Galactic center region at energies above 30 keV have revealed two strong y-ray sources. One source has been identified with X-ray 1E 1740.7-2942, located 0°.8 away from nucleus. If this is distance center, it one most luminous objects in galaxy from 35 to 200 keV. second consistent in location X-ray source GX 354 + 0 (MXB 1728- 34). In addition, flux 1 4 was marginally detected a level other post-1980 measurements. No significant hard or γ-ray was detected direction nucleus (Sgr A*), recently discovered γ-ray GRS 1758-258.
