Dust Properties of Clumpy Disc Galaxies at z~1.3 with Herschel-SPIRE
  We present the far-infrared derived dust properties from Herschel SPIRE of
the WiggleZ kinematic sample of 13 star-forming galaxies at z~1.3, with
existing ancillary ~kpc resolution integral field spectroscopy. We detect 3
galaxies individually and place limits on the remainder by stacking. The
detected galaxies, two clumpy discs and one merger, have cold dust temperatures
of ~26 K and have infrared luminosities of ~1.2x10^12 solar luminosities,
determined by modified blackbody fitting. The two detected disc galaxies have
the largest H\alpha surface areas of the sample and have the reddest
ultraviolet to near-infrared spectral energy distributions. The likely source
of the infrared luminosity in these objects is dust heated by the interstellar
radiation field and young stellar emission from the clumps within the discs.
The source of infrared luminosity for the merger is likely a dust heated by a
starburst resulting from the merger. The WiggleZ detections are among the
coldest and lowest luminosity individual objects detected in the far-infrared
at z>1. When combining the kinematic data, we find that none of the compact
galaxies nor the 'dispersion dominated' galaxies of the WiggleZ kinematic
sample are detected, implying that they have warmer dust temperatures. The
compact objects show the highest H\alpha velocity dispersions in the sample, in
qualitative agreement with bulge formation models. These far-infrared results
strengthen the interpretation that the majority of galaxies in this sample
constitute different stages in clumpy disc formation as presented from
ancillary kinematic analysis.
