Scientific paper

The Press-Schechter (1974) approximation is used to determine the abundance and large-scale clustering of dark haloes in the cold dark matter cosmogony. It is found that there exists a wide range of haloes which are both sufficiently massive and sufficiently numerous to host quasars, and that if the diffuse X-ray background is generated by discrete sources associated with dark haloes, then the halo masses are constrained to be less than 10 to the 12th/h solar masses. Two simple models for galaxy formation are considered.
