The South Pole Telescope has surveyed 1000 square degrees at millimeter wavelengths down to milli-Jansky levels with the aim of constraining cosmological parameters. One of the most interesting and unanticipated results of this survey was the discovery of a population of high redshift strongly lensed sub-millimeter galaxies (SMGs). The magnification of these objects and the long-wavelength selection makes these source the best window we have to directly investigate massive galaxy formation in the early universe. Here we propose to observe a flux-limited sample of 65 of these sources with PACS and SPIRE for a total of 25.6 hours. These observations will span the peak of the SEDs at all redshifts, determine the redshift distribution and temperatures for these sources, and enable detailed study of molecular and fine structure lines of high-redshift galaxies. These observations are the best method for constraining the properties of the highest redshift SMGs, and we expect to find a minimum of 3 sources at z>5. As these sources are in the southern hemisphere they are ideal targets for ALMA early science observations and will provide an invaluable sample of sources for the community.

Mission Description
Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
