Abstract (from CDS):

We present optical through radio observations of the host galaxies of two dust-obscured, luminous quasars selected in the mid-infrared, at z = 2.62 and z = 2.99, including a search for CO emission. Our limits on the CO luminosities are consistent with these objects having masses of molecular gas ≲ 1010 M☉, several times less than those of luminous submillimeter-detected galaxies at comparable redshifts. Their near-infrared spectral energy distributions, however, imply that these galaxies have high stellar masses (∼1011-1012 M☉). The relatively small reservoirs of molecular gas and low dust masses are consistent with them being relatively mature systems at high-z.
