On the Origin of the MeV Gamma-Ray Background
F. W. Stecker, M. H. Salamon, C. Done
In this paper, we suggest a new hypothesis for explaining the spectrum of the extragalactic MeV gamma-ray background as observed by COMPTEL and SMM. We propose that both the flux l…

F. W. Stecker, M. H. Salamon
We show that GLAST should be able to support or rule out the unresolved-blazar hypothesis for the origin of the diffuse, extragalactic gamma-ray background.

Gamma-Ray Absorption at High Redshifts and the Gamma-Ray Background
F. W. Stecker, M. H. Salamon
We present results of a calculation of absorption of 10-500 GeV gamma-rays at high redshifts. This calculation requires the determination of the high- redshift evolution of the ful…
