Abstract Deep surveys in the sub-mm waveband are revealing a population of very luminous dusty galaxies at high redshifts, $0.5 < z < 3$, which are; (a) as a population, producing stars at a rate as large or larger than the optically selected galaxy population at high redshifts and thus presumably producing a substantial (and perhaps dominant) fraction of all stars that have ever been produced; and (b) doing so, individually, in systems with bolometric luminosities (i.e. star-formation rates) that are very much larger than typically seen in the optically-selected population. Together, these suggest that the sub-mm sources represent a major phase of galaxy evolution that is not represented in the optically-selected samples. We are ed in a major study of this population using SCUBA on the JCMT. Existing $HST$ images are playing a crucial role in this work - both in revealing disturbed morphologies of the identifications and in simply identifying the optically faintest sources. But at present our $HST$ images only cover a modest fraction our two main survey areas, limiting the number of sub-mm sources that can be identified and studied in detail. We propose to observe additional fields in our survey areas to overcome this limitation. ------------------------------------------------------------------------------------ 8162( 3) - 02/18/99 16:17 - [ 2] Observations Description ------------------------ These observations are straightforward. Two allow for optimal co-addition, the three-orbit exposures will be split into five shorter exposures. There are no roll-angle constraints. The 3 orbit exposure time is requested to achieve the same depth as in our successful use of exisiting images for classification of source morphologies and faint source identifications.
