Abstract:
The rich information on (sub)millimeter dust continuum emission from
distant galaxies in the public Atacama Large Millimeter/submillimeter
Array (ALMA) archive is contained in thousands of inhomogeneous
observations from individual PI-led programs. To increase the
usability of these data for studies deepening our understanding of
galaxy evolution, we have developed automated mining pipelines for the
ALMA archive in the COSMOS field (A3COSMOS) that efficiently exploit
the available information for large numbers of galaxies across cosmic
time and keep the data products in sync with the increasing public
ALMA archive: (a) a dedicated ALMA continuum imaging pipeline, (b) two
complementary photometry pipelines for both blind source extraction
and prior source fitting, (c) a counterpart association pipeline
utilizing the multiwavelength data available (including quality
assessment based on machine-learning techniques), (d) an assessment of
potential (sub)millimeter line contribution to the measured ALMA
continuum, and (e) extensive simulations to provide statistical
corrections to biases and uncertainties in the ALMA continuum
measurements. Application of these tools yields photometry catalogs
with ∼1000 (sub)millimeter detections (spurious fraction ∼8%-12%) from
over 1500 individual ALMA continuum images. Combined with ancillary
photometric and redshift catalogs and the above quality assessments,
we provide robust information on redshift, stellar mass, and star
formation rate for ∼700 galaxies at redshifts 0.5-6 in the COSMOS
field (with undetermined selection function). The ALMA photometric
measurements and galaxy properties are released publicly within our
blind extraction, prior fitting, and galaxy property catalogs, plus
the images.
Description:
The pointings of all public Atacama Large Millimeter/submillimeter
Array (ALMA) data for the COSMOS field as of 2018 January 2 is shown
in Figure 2, overlaid on the Herschel Space Observatory Photodetector
Array Camera and Spectrometer (PACS) 100um image. The sum of the
primary beam area of these observations reaches 164arcmin2.

galaxies with optical/near-infrared detections, so that each galaxy
has a reasonably constrained, consistently fitted stellar mass, star
formation rate and redshift.
