| Description | The Herschel Reference Survey (HRS), the first unbiased survey of dust in early-type galaxies (ETGs), has provided insights into the evolution of both S0s and ellipticals. The small dust disks in S0s suggest that these galaxies are early-type spirals that have had their dust and gas removed by environmental processes such as ram-pressure stripping. The properties of the dust in the ellipticals imply that the dust in these has been acquired by gravitational interactions - a process that is likely to be more important in low-density environments. Although the optical properties of ETGs do not depend strongly on environment, in contradiction to the hierarchical paradigm, our results suggest that there should be a clear environmental signature in the properties of the dust. The volume of the HRS, however, is dominated by the Virgo Cluster, and so contains few ETGs in genuinely low-density environments. As a collaboration between the HRS and ATLAS3D teams, we propose to carry out an efficient Herschel survey of the much larger ATLAS3D sample, providing a legacy survey of four times as many ETGs as are in the HRS and extending our original survey to much sparser environments. Apart from its legacy value, we will answer four questions: 1) Are the small sizes of the dust disks in S0s the result of a current environmental process? 2) How do the properties of the dust in ETGs depend on the mass of stars in the galaxy? 3) Do the dust properties of the ellipticals display the clear environmental signature that the hierarchical paradigm requires? 4) How do the dust properties of the ETGs depend on the specific angular momentum of the stars, which has been measured for the ATLAS3D galaxies and may be more revealing of the basic physics of ETGs than the morphological classification of ellipticals and S0s? |

| 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. |
