dc.description.abstractWe analyze the dust properties of 57 870 mu m-selected dusty star-forming galaxies in GOODS-S using new deep Atacama Large Millimeter/Submillimeter Array 1.2, 2, and 3 mm continuum imaging together with other farinfrared through millimeter data. We fit the spectral energy distributions (SEDs) with optically thin modified blackbodies to constrain the emissivity indices and effective dust temperatures, finding a median emissivity index of beta=1.78(-0.25)(+0.43) and a median temperature of T-d =33.6(-5.4)(+12.1) K. We observe a negative correlation between beta and T-d. By testing several SED models, we determine that the derived emissivity indices can be influenced by opacity assumptions. Our temperature measurements are consistent with no evolution in dust temperature with redshift.
