Detecting massive star-forming galaxies at z>1 using BLAST and SCUBA-2 submillimetre wavelength surveys
We currently believe that we live in a Universe whose mass distribution is dominated by cold dark matter. This model does a remarkable job of explaining how the mild inhomogeneities in the primordial plasma, imprinted on the Cosmic Microwave Background, evolved into the complex web of large-scale structures observed in the local Universe. However, we are only just beginning to understand the details of how smaller objects such as stars, galaxies and clusters formed and evolved within the gravitational potential of dark matter. A crucial step in this process is to map out the distribution of light-emitting matter with redshift. While optical surveys using the Hubble Space Telescope and ground-based optical telescopes in the 1990's made great progress detecting "normal" galaxies to high redshifts (z>1), it has become clear during the last decade that longer wavelength studies in the IR--mm regime are required to detect galaxies in their earliest stages, as they are often optically obscured by dust, and hence absent from even the deepest optical images. I will discuss some recent Balloon-borne Large Aperture Submillimeter Telescope (BLAST) results from our 2006 campaign from McMurdo, Antarctica. I will also cover future surveys with the SPIRE camera for the Herschel Satellite, and the SCUBA-2 camera that will operate on the 15-m James Clerk Maxwell Telescope in Hawaii.
