Abstract: Luminous obscured AGN represent a key phase in the cosmic growth history of supermassive black holes. Since these AGN are rare, they can only be adequately sampled via wide-area surveys that probe a large volume of the Universe. “Stripe 82X,” an X-ray survey covering ~30 deg2 of the rich multi-wavelength Sloan Digital Sky Survey Stripe 82 field, is designed to uncover this population and constrain their evolution and impact on their host galaxies. In this talk, I will summarize the AGN demographics discovered in Stripe 82X and how they compare with AGN identified from wide-area optical and mid-infrared surveys. I will discuss what we have learned about the host galaxies of these luminous AGN and how the obscured AGN fraction evolves with redshift and luminosity. Finally, I will mention exciting future prospects for learning more about the cosmic evolution of rare (yet important!) high-redshift, high luminosity obscured AGN.
