| Description | A substantial fraction of the star-formation history of the Universe is encoded in the cosmic infrared background (CIB), but fundamental issues about the sources which make up the CIB such as their redshift distribution, their stellar masses, and the masses of their host halos remain poorly constrained by current measurements. To address these issues, we propose the Herschel Redshift Survey (HeRS), a 70 deg2 SPIRE survey in the SDSS Stripe 82. HeRS is designed to leverage the unprecedented spectroscopic redshift and stellar mass catalogs of the Hobby Eberly Telescope Dark Energy Experiment (HETDEX) and Spitzer-HETDEX Exploratory Large Area (SHELA) Survey, in order to provide the most precise constraints yet obtained on the obscured star-formation properties of galaxies in the redshift range 1.8 < z < 3.5. HeRS will principally target two goals: i) the redshift distribution of the infrared light that makes up the cosmic infrared background; and ii) the evolution of the specific star-formation rate of galaxies as a function of redshift. Our measurements will far outstrip any that could be made with existing or planned SPIRE surveys because the high level of confusion noise (330 times higher than the signal)requirescross-correlating maps with the highest quality ancillary data: specifically, data that provides extremely accurate redshifts and reliable stellar mass estimates over a wide area. And only HETDEX spectroscopic redshifts are capable of measuring the density field and bias to the required 12% accuracy. These measurements will break the luminosity-redshift degeneracy plaguing the interpretation of correlation studies of the CIB, and place tight constraints on source population models. This observing cycle represents the last chance to obtain Herschel observations of what will be one of the premier cosmological fields for years to come. |

| 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. |
