The luminosity function of Seyfert 1 galaxy nuclei and BL Lac objects, and the X-ray background
The luminosity function of Seyfert 1 and BL Lac object nuclei is constructed. The main results of this study are that: The luminosity function of Seyfert 1 nuclei is steep, which implies a rather large volume density of such nuclei fainter than M/sub v/=-18 (using H/sub o /=50 km s/sup -1//Mpc). The...
