Infrared Classification and Luminosities For Dusty AGN and the Most
  Luminous Quasars
  Mid-infrared spectroscopic measurements from the Infrared Spectrometer on
Spitzer (IRS) are given for 125 hard X-ray AGN (14-195 keV) from the Swift
Burst Alert Telescope sample and for 32 AGN with black hole masses from
reverberation mapping. The 9.7 um silicate feature in emission or absorption
defines an infrared AGN classification describing whether AGN are observed
through dust clouds, indicating that 55% of the BAT AGN are observed through
dust. The mid-infrared dust continuum luminosity is shown to be an excellent
indicator of intrinsic AGN luminosity, scaling closely with the hard X-ray
luminosity, log vLv(7.8 um)/L(X) = -0.31 +- 0.35 and independent of
classification determined from silicate emission or absorption. Dust luminosity
scales closely with black hole mass, log vLv(7.8 um) = (37.2 +- 0.5) + 0.87 log
BHM for luminosity in erg per sec and BHM in solar masses. The 100 most
luminous type 1 quasars as measured in vLv(7.8 um) are found by comparing Sloan
Digital Sky Survey optically discovered quasars with photometry at 22 um from
the Wide-Field Infrared Survey Explorer, scaled to rest frame 7.8 um using an
empirical template determined from IRS spectra. The most luminous SDSS/WISE
quasars have the same maximum infrared luminosities for all 1.5 < z < 5,
reaching total infrared luminosity L(IR) = 10^14.4 solar luminosities.
Comparing with Dust Obscured Galaxies from Spitzer and WISE surveys, we find no
evidence of hyperluminous obscured quasars whose maximum infrared luminosities
exceed the maximum infrared luminosities of optically discovered quasars.
Bolometric luminosities L(bol) estimated from rest frame optical or ultraviolet
luminosities are compared to L(IR).
