What is Deep Sub-millimeter Surveys and the Hidden Phases of Galaxy Formation about?

Deep surveys in the far-infrared and sub-millimeter wavebands are revealing a new phase of galactic evolution hidden by dust. Observations with SCUBA on the JCMT show that 25% of the COBE/FIRAS background at 850 microns is being produced by high luminosity sources (L ~ 3x10^12 L_sun) at high redshifts 0.5 < z < 3+. These sources have an estimated redshift distribution that is broadly consistent with a global star-formation history that is similar to that inferred from optical observations. The sub-mm galaxies and optically selected galaxies are producing comparable quantities of stars. However, the sub-mm sources are doing so in systems that have luminosities that are an order of magnitude higher, and comoving densities an order of magnitude lower, then the optically selected galaxies. These high luminosity sources are plausibly responsible for producing the spheroidal components of massive galaxies at z ~ 2.
