| Description |
Large-area, multi-wavelength surveys from the ground and space have discovered a new population of strongly lensed, dusty, star-forming galaxies (DSFGs).
These sources have lensing magnifications of x10-50 and present an exciting new means of studying otherwise faint high-redshift contributors to the cosmic infrared background (CIB) in exquisite detail.
With its large survey area and long-wavelength selection, the South Pole Telescope (SPT) selects the rarest, brightest, and most interesting sample the sample of strongly lensed DSFGs and is enabling major advances in our understanding of massive galaxy formation.
Here we request 16.9 hours of SPIRE and PACS imaging to followup a sample of 88 sources from a 1.4 mm flux-limited sample with the aim of constraining SEDs to 1) estimate photometric redshifts, 2) measure dust temperatures, 3) derive the apparent and intrinsic IR luminosities, and 4) accurately determine molecular and atomic line to luminosity ratios. This proposal is part of a systematic followup campaign which includes approved and ongoing programs with HST, VLT, Spitzer, APEX, ATCA, and ALMA early science observations. |
