X-ray & WISE AGN in the 37 deg2 SDSS-IV eBOSS Survey of Stripe 82
Abstract
We summarize the results of a SDSS-IV eBOSS program to spectroscopically target WISE AGN candidates and X-ray sources in a ~37 deg2 area of Stripe 82, ~15.5 deg2 of which overlaps the largest contiguous portion of the Stripe 82 X-ray survey. This survey represents the largest spectroscopic survey of AGN selected on the basis of their WISE W1 - W2 colors and more than doubles the number of optically obscured X-ray and WISE AGN in the survey field. While the X-ray AGN detected by WISE and have WISE W1-W2 colors that do not meet the AGN color definition tend to be at low redshift (z < 1) and luminosity (Lx < 1044 erg/s), about a quarter of the most luminous X-ray AGN (> 1044 erg/s) at z > 1 are undetected by WISE. Approximately 70% of the WISE AGN are undetected by the X-ray observations in the field, though nearly half of the WISE AGN at z < 0.5 could potentially be star forming galaxies and not AGN.
