Phil Hopkins (Harvard) spoke here today about systematically fitting all AGN luminosity functions at all wavelengths by convolving a bolometric luminosity function with the observed range (different at each luminosity) of spectral energy distributions and dust attenuations. His fits look great, and make many predictions. In an aside, he noted that the faint end of the AGN luminosity function at high redshift may well be set by the fading power-law of the AGN after its high-luminosity event. If so, this would be an application of the idea in this obscure paper.
