Abstract (from CDS):

Using the Australia Telescope Compact Array, we conducted a survey of CO J=1 - 0 and J=2 - 1 line emission towards strongly lensed high-redshift dusty star-forming galaxies (DSFGs) previously discovered with the South Pole Telescope (SPT). Our sample comprises 17 sources that had CO-based spectroscopic redshifts obtained with the Atacama Large Millimeter/submillimeter Array and the Atacama Pathfinder Experiment. We detect all sources with known redshifts in either CO J=1 - 0 or J=2 - 1. 12 sources are detected in the 7-mm continuum. The derived CO luminosities imply gas masses in the range (0.5-11) x 1010 M☉ and gas depletion time-scales tdep z=2-5 in the SPT DSFG sample.
