Abstract
We present the complete submillimeter data for the Canada-UK Deep Submillimeter Survey with SCUBA on the JCMT. We have imaged two fields, covering approximately 100 square arcminutes and have assembled a sample of 50 objects with S850um > 3 mJy. The objects discovered in this work, and through other surveys with SCUBA, are broadly consistent in spectral energy distribution with the local ultra-luminous infrared galaxies but are much more common at high-redshift. They are forming stars at unprecedented rates of ~1000 Mo/yr. We discuss the source counts and angular clustering properties of these objects in the context of galaxy formation. We have a marginal detection of strong clustering, which suggests these objects formed in the most massive dark halos of the early universe. We summarize the current identifications and redshifts of these galaxies, determined through optical, near-IR, far-IR, radio and 450um data. We find ~10% of the objects lie at z < 1 and estimate a mean redshift for the population of z ~2. In line with other surveys, we are finding a small but significant fraction of sources are identified with Extremely Red Objects and Lyman-break galaxies.
