Abstract:
We present deep SCUBA-2 450µm imaging of the two GOODS fields,
achieving a central rms of 1.14mJy for the GOODS-N and 1.86mJy for the
GOODS-S. For each field, we give a catalog of >4σ detections (79
and 16 sources, respectively). We construct the 450µm number
counts, finding excellent agreement with others from the literature.
We match the 450µm sources to 20cm data (both fields) and ALMA
870µm data (GOODS-S) to gauge the accuracy of the 450µm
positions. We use the extensive redshift information available on the
fields to test how well redshift can be estimated from simple flux
ratios (450µm/850µm and 20cm/850µm), finding tight
correlations. We provide a catalog of candidate high-redshift
submillimeter galaxies. We look for evolution in dust temperature with
redshift by fitting the spectral energy distributions of the sources,
but we do not find any significant redshift evolution after accounting
for the far-infrared luminosity. We do not find evidence for the
450µm selection picking out warmer sources than an 850µm
selection. We find that a 450 µm-selected sample only adds
low-redshift (z<1.5) galaxies beyond an 850µm sample.
Description:
In Cowie+ (2018, J/ApJ/865/106), we presented SCUBA-2 850um catalogs
(>4σ) of the GOODS-N and GOODS-S through mid-2016 and through
early 2017, respectively. We also presented a SCUBA-2 450um catalog
(>4σ) of the GOODS-N.
We have continued to deepen our observations. See Section 2.1.
We have been compiling spectroscopic redshifts from our own Keck
observations and from the literature for sources in the GOODS fields
for many years, so we have a large database from which to draw to find
redshifts. See Section 2.6.

Note (1): Two of the 450um sources are blended at 850um, so the number in this
column is the 450um source number of the brighter source in the pair
to which we assigned all of the measured 850um flux.
Note (2): Flag as follows:
s = spectroscopic redshift, specz, see Section 2.6 for references
p = photometric redshift, photz; two significant figures
c = the photometry is contaminated by a neighboring star or galaxy
