A current question in the co-evolution of black holes and galaxies concerns the observed growth phase of black holes and how this might relate to the star formation histories of their host galaxies. Results are presented here based on samples of high-redshift obscured active galaxies that have been selected from several current large multi-wavelength surveys, including GOODS, AEGIS and COSMOS. The ability to combine deep, wide imaging obtained with HST, Chandra, Spitzer and ground-based facilities provides opportunities to select new samples of obscured AGN at high redshift that are faint or undetected at optical wavelengths but well detected in the infrared and X-rays. Together with deep spectroscopy programs, these observations are used to understand the spectral energy distributions of the sources and constrain the properties of their host galaxies as well as their central black holes. The results are used to examine the evolution of the AGN luminosity function up to high redshift, with corresponding implications for the co-evolution of galaxies and their central supermassive black holes.
