Abstract

We present a determination of the optical/UV AGN luminosity function and its evolution, based on a large sample of faint (R < 24) QSOs identified in the COMBO-17 survey. Using multi-band photometry in 17 filters within 350 nm < λobs < 930 nm, we could simultaneously determine photometric redshifts with an accuracy of σ z ≃ 0.03 and obtain spectral energy distributions. We select a sample covering the redshift range across 1.2 < z < 4.8. Even at z ≃ 3, the sample reaches below luminosities corresponding to M B = –23, conventionally employed to distinguish between Seyfert galaxies and quasars.
