Accurate Positions for Rare and Bright Dusty Star Forming Galaxies Discovered with the South Pole Telescope
Abstract
The South Pole Telescope (SPT) has recently discovered a new population of extraordinarily bright, dusty, star-forming galaxies in a wide field millimeter-wave survey of the southern sky. Our extensive follow-up campaign indicates that they are high-redshift, strongly-lensed, sub-mm galaxies (SMGs). ATCA is playing a central role in these observations by providing precise locations and in some cases resolving multiple images. Here we propose observations of 6 targets from 2008 SPT observations. ATCA imaging will provide unambiguous identification of the IR counterparts of these sources and enable spectroscopic followup, and resolve lensed structure in several sources. Only through these observations can we advance our understanding of these objects and use them to probe extreme galaxy formation processes in the early universe.
