Pulsars and the Distribution of Celestial Gamma Rays

Abstract

The flux of celestial gamma rays from discrete sources (for example, pulsars) is calculated, showing that these sources emit fluxes of several ${10}^{-6\mathrm{}}$ quanta/${\mathrm{cm}}^2$ sec over regions of several tens of degrees (among them Vela X). Hence they should be observable. The calculations show further that the high gamma-ray flux values of OSO-III follow from the expected correlation of cosmic-ray sources with regions of large hydrogen density.
