The Future of Millimetre and Submillimetre Cosmology
David H. Hughes
Abstract
Using the submm array camera SCUBA on the 15-m JCMT it is now possible to conduct unbiased submm surveys and quantify the level of star-formation activity in the young Universe by observing the rest-frame FIR thermal emission from dust in high-redshift galaxies. However an accurate interpretation of these existing submm cosmological surveys is prevented by uncertainties in the redshifts of the submm-selected galaxies, the ambiguities in the identifications of their optical/IR and radio counterparts and the restricted range of flux density over which the submm source-counts are measured. This paper outlines the future observations required to overcome these deficiencies.
