Abstract:
The Wide-field Infrared Survey Explorer (WISE) mission has unveiled a
rare population of high-redshift (z=1-4.6), dusty, hyper-luminous
galaxies, with infrared luminosities LIR>1013L☉, and
sometimes exceeding 1014L☉. Previous work has shown that their
dust temperatures and overall far-infrared spectral energy
distributions (SEDs) are significantly hotter than expected to be
powered by star formation. We present here an analysis of the
rest-frame optical through mid-infrared SEDs for a large sample of
these so-called "hot, dust-obscured galaxies" (Hot DOGs).
Description:
We obtained observations of WISE "hot, dust-obscured galaxies" (Hot
DOGs) with the IRAC instrument onboard the Spitzer Space Telescope.
We obtained follow-up near-infrared observations of our sample using
the Wide-field IR Camera (WIRC) on the Hale 200 inch telescope at
Palomar Mountain, the WIYN High-resolution Infrared Camera (WHIRC) at
the 3.5m WIYN telescope, the Ohio State InfraRed Imager/Spectrometer
(OSIRIS) at the 4m SOAR telescope, and the SAO Widefield InfraRed
Camera (SWIRC) at the 6.5m MMT telescope. (See table 2).
Optical spectroscopy was performed for a large fraction of our sample
using several facilities.
