SCUBA-2 850{mu}m component of JINGLE
Listed in IVOA Registry (Virtual Observatory)
We present the SCUBA-2 850{mu}m component of JINGLE, the new JCMT large survey for dust and gas in nearby galaxies, which with 193 galaxies is the largest targeted survey of nearby galaxies at 850{mu}m.
Description
We provide details of our SCUBA-2 data reduction pipeline, optimized for slightly extended sources, and including a calibration model adjusted to match conventions used in other far-infrared (FIR) data. We measure total integrated fluxes for the entire JINGLE sample in 10 infrared/submillimetre bands, including all WISE, Herschel-PACS, Herschel-SPIRE, and SCUBA-2 850{mu}m maps, statistically accounting for the contamination by CO(J=3-2) in the 850{mu}m band.
Of our initial sample of 193 galaxies, 191 are detected at 250{mu}m with a >=5{sigma} significance. In the SCUBA-2 850{mu}m band we detect 126 galaxies with >=3{sigma} significance. The distribution of the JINGLE galaxies in FIR/sub-millimetre colour-colour plots reveals that the sample is not well fit by single modified-blackbody models that assume a single dust-emissivity index ({beta}).

Instead, our new 850{mu}m data suggest either that a large fraction of our objects require {beta}<1.5, or that a model allowing for an excess of sub-mm emission (e.g. a broken dust emissivity law, or a very cold dust component~<10K) is required. We provide relations to convert FIR colours to dust temperature and {beta} for JINGLE-like galaxies. For JINGLE the FIR colours correlate more strongly with star-formation rate surface-density rather than the stellar surface-density, suggesting heating of dust is greater due to younger rather than older stellar-populations, consistent with the low proportion of early-type galaxies in the sample.
