Abstract (from CDS):

We estimate the relative contributions of the supermassive black hole (SMBH) accretion disk, corona, and obscuring torus to the bolometric luminosity of Seyfert galaxies, using Spitzer mid-infrared (MIR) observations of a complete sample of 68 nearby active galactic nuclei (AGNs) from the INTEGRAL all-sky hard X-ray (HX) survey. This is the first HX-selected (above 15 keV) sample of AGNs with complementary high angular resolution, high signal-to-noise, MIR data. Correcting for the host galaxy contribution, we find a correlation between HX and MIR luminosities: L_15 µm∝L0.74±0.06^HX. Assuming that the observed MIR emission is radiation from an accretion disk reprocessed in a surrounding dusty torus that subtends a solid angle decreasing with increasing luminosity (as inferred from the declining fraction of obscured AGNs), the intrinsic disk luminosity, LDisk, is approximately proportional to the luminosity of the corona in the 2-300 keV energy band, LCorona, with the LDisk/LCorona ratio varying by a factor of 2.1 around a mean value of 1.6. This ratio is a factor of ∼2 smaller than for typical quasars producing the cosmic X-ray background. Therefore, over three orders of magnitude in luminosity, HX radiation carries a large, and roughly comparable, fraction of the bolometric output of AGNs. We estimate the cumulative bolometric luminosity density of local AGNs at ~(1-3)x1040 erg/s M/pc3. Finally, the Compton temperature ranges between kTc~ 2 and ~6 keV for nearby AGNs, compared to kTc~ 2 keV for typical quasars, confirming that radiative heating of interstellar gas can play an important role in regulating SMBH growth.
