Stripe 82 X: Archival XMM Newton- And Chandra-selected AGN In SDSS Stripe 82
Abstract
Multiwavelength surveys have proved very powerful tools for studying galaxies, AGN, and clusters. A "wedding cake" (i.e., tiered) strategy of depth and area samples a wide range of luminosity and redshift, essential for disentangling evolution- and mass-based effects. The study of AGN requires X-rays, and deep X-ray surveys have been a critical part of highly productive multiwavelength surveys like GOODS, COSMOS, Lockman, AEGIS, MUSYC, and Bootes. Most of these surveys cover too small an area to sample rare objects like high luminosity or high redshift AGN, however, so larger surveys are needed to those regimes. Using archival XMM and Chandra data in Stripe 82, along with SDSS spectra and other multiwavelength data for cross-matched sources, we present AGN number counts and the redshift and luminosity distributions. These data constrain the luminosity function and evolution of X-ray-selected AGN in areas of parameter space that have been poorly sampled to date.
