The contribution of accreting black holes to the background radiation density.
Abstract
Black-hole accretion and radiation from accreting black holes are discussed. The radiation produced by black holes in the present epoch is considered, and limits are placed on the background radiation density associated with black-hole accretion in pregalactic epochs. Pregalactic accretion limits are also obtained. It is concluded that the pregalactic accretion limit is not as strong as might be expected and is generally weaker than the limit for the present epoch.
