Abstract:
We systematically investigate the near- to far-infrared (FIR)
photometric properties of a nearly complete sample of local active
galactic nuclei (AGNs) detected in the Swift/Burst Alert Telescope
(BAT) all-sky ultra-hard X-ray (14-195keV) survey. Out of 606
non-blazar AGNs in the Swift/BAT 70 month catalog at high galactic
latitudes of |b|>10°, 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<logL14-195<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. We also show that
the completeness of the WISE color-color cut in selecting Swift/BAT
AGNs increases strongly with 14-195keV luminosity.
Description:
Our initial sample contains the 834 AGNs reported in the 70 month
Swift/BAT catalog (Baumgartner+ 2013, J/ApJS/207/19), 105 of which are
blazars. Of the remaining 729 sources, 697 sources have secure
redshift information as presented in Ricci et al. (2016, ApJ,
submitted). Next, we removed galaxy pairs or interacting galaxies not
resolved in the BAT survey. Further, the 606 sources located at higher
galactic latitudes with |b|>10° were selected to reduce the
contamination in the crowded region through IR catalog matching.
