| Description | We propose Herschel spectroscopic observations of the C II158 um and O I63um emission lines in 4 extremely bright, lensed, high-redshift galaxies.Herschel photometric surveys conducted toward galaxy clusters have identifiedthese highly magnified sources, which would otherwise be undetectable belowthe confusion limit of the instrument. These exceptional targets provide theunique opportunity to study the characteristics of the ISM in typical galaxieswith moderate luminosities at high redshift.Recent studies have identified key differences between the far-infraredproperties of local LIRGS/ULIRGS and galaxies of comparable luminosity at highredshift. However, the highest redshift observations are inherently biasedtoward more luminous galaxies, making it difficult to extend this comparison tothe abundant population which is intrinsically faint. Herschel spectroscopy ofhighly magnified galaxies provides the only means to probe the physicalconditions within this more typical population. Measurements of the C II andO I cooling lines are sensitive to the temperature and density of the gassurrounding starforming regions, as well as the strength of the incidentfar ultraviolet radiation from starbursts. These observations will provideinsight into the environmental conditions that drive the differences betweenhigh-redshift star-forming galaxies and those in the local universe. |

| 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. |
