350μm Observations of Local IRAS Galaxies Using SHARC-II

Abstract

The cosmologically significant population of dusty galaxies detected at sub-mm and mm wavelengths by SCUBA and MAMBO have played a central part in many of the discussions at this workshop. Obtaining their redshifts is critical in understanding their role in galaxy formation and evolution, but this is a challenging task. Nevertheless, Chapman et al. [1] have made significant process by obtaining spectroscopic redshifts of the subset of sub-mm galaxies detected in deep radio images that have optical counterparts. This exploits the well-known Far-Infrared/Radio correlation, and allows the high resolution radio maps to be used as a surrogate for finding the correct optical counterpart for which spectroscopy can then be attempted.
