Obscuration and clustering of AGN in the 9 deg2 Bootes survey

Ryan Hickox

Unified and evolutionary models of active galactic nuclei (AGN) indicate that a significant fraction of luminous AGN are obscured by gas and dust. It is also increasingly clear that AGN play a key role in the evolution of their host galaxies. I will discuss two studies of AGN that address these topics, using data from the 9 square degree multiwavelength survey in Bootes. First, we use mid-IR selection to identify a large population of luminous, obscured AGN ("Type 2 quasars") at 0.7
