Description One of the major discoveries in the IR and sub-mm wavelengths are the so-called sub-mm galaxies (SMGs). These high-redshift, optically obscured, star-forming galaxies account for more than half of the far-infrared background and their star-formation rates are orders of magnitudes higher than most galaxies in the local Universe. SMGs are considered the precursors of today.s most massive elliptical or bulge galaxies and are amongst the most difficult obstacles for models of galaxy formation and evolution. They may provide clues for understanding the formation and evolution of galaxies in the very early Universe - one of the most challenging and important topics in astrophysics. Wide area surveys, like the Herschel Astrophysical Teraherz Large Area Survey (H-ATLAS) - the largest Herschel Open Time Key Programme, will detect a significant number of SMGs at z>2. We propose SPIRE Fourier-Transform Spectrometer (FTS) follow-up of the first two H-ATLAS SMG identified during the Herschel Science Demonstration Phase. Both targets HATLAS 81 and HATLAS 130 are lensed by foreground galaxies and are already subject to ground-based and HST follow-up observation. Radio-mm observations at CSO-Zspec and GBT-Zpectrometer secured their spectroscopic redshifts at 3.04 and 2.625 respectively, based on CO lines. The proposed SPIRE FTS observations will result in the deepest spectra of SMGs in 197-670 microns band (corresponding to ~50-170 microns rest-frame), achieving line sensitivity of 10^{-17} W-m2 (5-sigma) and continuum at signal-to-noise greater than 4. This will enable us to constrain the physical conditions of the ISM using a combination of the the atomic cooling lines, the total IR luminosity, and the CO spectral-line energy distribution obtained from radio-mm ground-based observations. In order to better constrain the blue wing of the SED peak we also add short PACS mini-maps around each source, going down to 10 and 15 mJy (5-sigma) at 100 and 160 microns.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
