Abstract:
We quantify the luminosity contribution of active galactic nuclei
(AGNs) to the 12µm, mid-infrared (MIR; 5-38µm), and total IR
(5-1000µm) emission in the local AGNs detected in the all-sky 70
month Swift/Burst Alert Telescope (BAT) ultrahard X-ray survey. We
decompose the IR spectral energy distributions (SEDs) of 587 objects
into the AGN and starburst components using templates for an AGN torus
and a star-forming galaxy. This enables us to recover the emission
from the AGN torus including the low-luminosity end, down to
log(L14-150/erg/s)∼41, which typically has significant host galaxy
contamination. The sample demonstrates that the luminosity
contribution of the AGN to the 12µm, the MIR, and the total IR
bands is an increasing function of the 14-150keV luminosity. We also
find that for the most extreme cases, the IR pure-AGN emission from
the torus can extend up to 90µm. The total IR AGN luminosity
obtained through the IR SED decomposition enables us to estimate the
fraction of the sky obscured by dust, i.e., the dust covering factor.
We demonstrate that the median dust covering factor is always smaller
than the median X-ray obscuration fraction above an AGN bolometric
luminosity of log(Lbol(AGN)/erg/s)∼42.5. Considering that the
X-ray obscuration fraction is equivalent to the covering factor coming
from both the dust and gas, this indicates that an additional neutral
gas component, along with the dusty torus, is responsible for the
absorption of X-ray emission.
Description:
Our initial sample is based on the sample of
Ichikawa+ (2017, J/ApJ/835/74), which contains the 606 non-blazar AGNs
from the Swift/BAT 70 month catalog (Baumgartner+ 2013, J/ApJS/207/19)
at galactic latitudes (|b|>10°) for which secure spectroscopic
redshifts are available. In this study, we use the column density
(NH) and the absorption-corrected 14-150keV luminosity (L14-150)
tabulated in Ricci+ (2017, J/ApJS/233/17).
