AbstractDiffuse Galactic gamma-ray flux resulting from the evaporation of primordial black holes has been the subject of intensive research work during the last few decades. Theoretical work addressing this issue started in the 1970s whereas data started pouring in only in the 1990s. We discuss in this paper a model of the potential contribution to the Galactic gamma-ray flux of primordial black holes in binary systems and extend the argument to include stable gravitational bound states called Holeums. The model has a predictive power and can be tested by looking for gamma-ray excess in the vicinity of violent events occurring in the Galaxy such as supernova explosions.
