| Description | We propose to make deep PACS observations of a 1.75-square degree region of the Coma cluster which encompasses both the dense core and the southwest infall region, and covers a factor of 100 in galaxy density. In combination with SPIRE data from the Herschel-ATLAS Key Project, these data will provide the first reliable measurements of the dust properties in a rich galaxy cluster. We have assembled a vast multi-wavelength dataset over this region of Coma that has allowed us to compute reliable stellar masses for nearly 2,000 spectroscopically-confirmed cluster members. We will (i) measure the far-infrared luminosity function and determine whether the turnover seen in Virgo is also present in Coma; (ii) measure the dust masses and temperatures of all galaxies brighter than this turnover; (iii) derive reliable *total* star-formation rates for all galaxies from a combination of UV, H-alpha, and far-IR imaging, and hence address the controversy surrounding optically-classified post-starburst galaxies; (iv) relate these important properties of the cluster galaxies to quantities such as stellar mass, galaxy morphology, local galaxy density, and the density of the intra-cluster medium, to determine which physical processes are responsible for the transformation of galaxies from late-type to early-type. We will also search for intra-cluster dust which is expected to be produced via stripping of material from infalling galaxies. |

| 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. |
