Query: Interferometric Follow-Up of WISE Hyper-Luminous Hot, Dust-Obscured
  Galaxies   WISE has discovered an extraordinary population of hyper-luminous dusty
galaxies which are faint in the two bluer passbands ($3.4\, \mu$m and $4.6\,
\mu$m) but are bright in the two redder passbands of WISE ($12\, \mu$m and
$22\, \mu$m). We report on initial follow-up observations of three of these
hot, dust-obscured galaxies, or Hot DOGs, using the CARMA and SMA
interferometer arrays at submm/mm wavelengths. We report continuum detections
at $\sim$ 1.3 mm of two sources (WISE J014946.17+235014.5 and WISE
J223810.20+265319.7, hereafter W0149+2350 and W2238+2653, respectively), and
upper limits to CO line emission at 3 mm in the observed frame for two sources
(W0149+2350 and WISE J181417.29+341224.8, hereafter W1814+3412). The 1.3 mm
continuum images have a resolution of 1-2 arcsec and are consistent with single
point sources. We estimate the masses of cold dust are 2.0$\times 10^{8}
M_{\odot}$ for W0149+2350 and 3.9$\times 10^{8} M_{\odot}$ for W2238+2653,
comparable to cold dust masses of luminous quasars. We obtain 2$\sigma$ upper
limits to the molecular gas masses traced by CO, which are 3.3$\times 10^{10}
M_{\odot}$ and 2.3$\times 10^{10} M_{\odot}$ for W0149+2350 and W1814+3412,
respectively. We also present high-resolution, near-IR imaging with WFC3 on the
Hubble Space Telescope for W0149+2653 and with NIRC2 on Keck for W2238+2653.
The near-IR images show morphological structure dominated by a single,
centrally condensed source with effective radius less than 4 kpc. No signs of
gravitational lensing are evident.
