The Space Density of X-ray Selected AGN in Stripe 82
Abstract
The large survey area of Stripe 82 allows for the inclusion of rare high luminosity and high redshift AGN that are under-represented in deep, smaller area surveys. Based on matching archival XMM-Newton and Chandra data to the Sloan Digital Sky Survey, we compare the number counts of X-ray selected AGN in Stripe 82 to smaller, lower-luminosity samples from the Chandra Deep Fields, GOODS, COSMOS, and AEGIS. We differentiate between obscured and unobscured AGN in Stripe 82 and model these populations with an evolving luminosity function. Finally, we comment on the high luminosity end of the X-ray selected quasar luminosity function, probing a population previous surveys are unable to explore fully.
