An ALMA survey of the SCUBA-2 CLS UDS field: Physical properties of 707 Sub-millimetre Galaxies

Understand

We analyse the physical properties of a large, homogeneously selected sample of ALMA-located sub-mm galaxies (SMGs).

• This survey, AS2UDS, identified 707 SMGs across the ~1 sq.deg.
• field, including ~17 per cent, which are undetected at $K$>~25.7 mag.
• We interpret their ultraviolet-to-radio data using MAGPHYS and determine a median redshift of z=2.61+-0.08 (1$\sigma$ range of z=1.8-3.4) with just ~6 per cent at z>4.
