BEARS II ALMA observations of HerBS source field
Listed in IVOA Registry (Virtual Observatory)
We present 101- and 151-GHz ALMA continuum images for 85 fields selected from Herschel observations that have 500-{mu}m flux densities >80 mJy and 250-500-{mu}m colours consistent with z > 2, most of which are expected to be gravitationally lensed or hyperluminous infrared galaxies.
Description
Approximately half of the Herschel 500-{mu}m sources were resolved into multiple ALMA sources, but 11 of the 15 brightest 500-{mu}m Herschel sources correspond to individual ALMA sources.
For the 37 fields containing either a single source with a spectroscopic redshift or two sources with the same spectroscopic redshift, we examined the colour temperatures and dust emissivity indices. The colour temperatures only vary weakly with redshift and are statistically consistent with no redshift-dependent temperature variations, which generally corresponds to results from other samples selected in far-infrared, submillimetre, or millimetre bands but not to results from samples selected in optical or near-infrared bands.

The dust emissivity indices, with very few exceptions, are largely consistent with a value of 2. We also compared spectroscopic redshifts to photometric redshifts based on spectral energy distribution templates designed for infrared-bright high-redshift galaxies. While the templates systematically underestimate the redshifts by ~15 per cent, the inclusion of ALMA data decreases the scatter in the predicted redshifts by a factor of ~2, illustrating the potential usefulness of these millimetre data for estimating photometric redshifts.
