IR photometry of AGNs in Swift/BAT 70 month cat.

Out of 606 non-blazar AGNs in the Swift/BAT 70 month catalog at high galactic latitudes of |b|>10{deg}, we obtain IR photometric data of 604 objects by cross-matching the AGN positions with catalogs from the WISE, AKARI, IRAS, and Herschel infrared observatories.

We find a good correlation between the ultra-hard X-ray and mid-IR luminosities over five orders of magnitude (41<logL_14-195_<46). Informed by previous measurements of the intrinsic spectral energy distribution of AGNs, we find FIR pure-AGN candidates whose FIR emission is thought to be AGN-dominated with low star-formation activity. We demonstrate that the dust covering factor decreases with the bolometric AGN luminosity, confirming the luminosity-dependent unified scheme.
