摘要：

Pregalactic black holes accrete matter in the early universe and produce copious amounts of x radiation. By using observations of the background radiation in the x and γ wavebands we have been able to impose a strong new constraint upon their possible abundance. If pregalactic black holes are actually present, several outstanding problems of cosmogony can be resolved with typical pregalactic black hole masses of 100M⊙. Significantly more massive holes cannot constitute an appreciable mass fraction of the universe and are limited by ΩPGBH(M)<10(M⊙JM)Ω-1. © 1979 Plenum Publishing Corporation.
