Scientific paper

Rapid advances in gamma-ray astronomy now permit better estimates of the photoproduction of hard gravitons by some Galactic and extragalactic sources. The energies considered range mainly from 0.5 to 200 MeV for both photons and gravitons. The corresponding graviton luminosities can be as high as to the 27th erg/s for Cygnus X-3, 10 to the 22nd erg/s for the Vela, and 10 to the 23rd erg/s for the Crab. For the Galactic center the graviton luminosity 10 to the 23rd erg/s is comparable with that produced by infrared photons.
