The Geometry of the Infrared and X-ray Obscurer in a Dusty Hyperluminous
  Quasar
  We study the geometry of the AGN obscurer in IRAS 09104+4109, an IR-luminous,
radio-intermediate FR-I source at $z=0.442$, using infrared data from Spitzer
and Herschel, X-ray data from Nustar, Swift, Suzaku, and Chandra, and an
optical spectrum from Palomar. The infrared data imply a total rest-frame
1-1000$\mu$m luminosity of $5.5\times10^{46}$erg s$^{-1}$ and require both an
AGN torus and starburst model. The AGN torus has an anisotropy-corrected IR
luminosity of $4.9\times10^{46}$erg s$^{-1}$, and a viewing angle and half
opening angle both of approximately $36$ degrees from pole-on. The starburst
has a star formation rate of $(110\pm34)$M$_{\odot}$ yr$^{-1}$ and an age of
$<50$Myr. These results are consistent with two epochs of luminous activity in
09104: one approximately $150$Myr ago, and one ongoing. The X-ray data suggest
a photon index of $\Gamma \simeq 1.8$ and a line-of-sight column of $N_{\rm H}
\simeq 5\times10^{23}$cm$^{-2}$. This argues against a reflection-dominated
hard X-ray spectrum, which would have implied a much higher $N_{\rm H}$ and
luminosity. The X-ray and infrared data are consistent with a bolometric AGN
luminosity of $L_{\rm bol}\sim(0.5-2.5)\times10^{47}$erg s$^{-1}$. The X-ray
and infrared data are further consistent with coaligned AGN obscurers in which
the line of sight "skims" the torus. This is also consistent with the optical
spectra, which show both coronal iron lines and broad lines in polarized but
not direct light. Combining constraints from the X-ray, optical, and infrared
data suggests that the AGN obscurer is within a vertical height of $20$pc, and
a radius of $125$pc, of the nucleus.
