We propose to make deep PACS observations of a 1.75-square degreeregion of the Coma cluster which encompasses both the dense core andthe 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 dustproperties in a rich galaxy cluster. We have assembled a vastmulti-wavelength dataset over this region of Coma that has allowed usto compute reliable stellar masses for nearly 2,000spectroscopically-confirmed cluster members. We will (i) measure thefar-infrared luminosity function and determine whether the turnoverseen in Virgo is also present in Coma; (ii) measure the dust massesand temperatures of all galaxies brighter than this turnover; (iii)derive reliable *total* star-formation rates for all galaxies from acombination of UV, H-alpha, and far-IR imaging, and hence address thecontroversy surrounding optically-classified post-starburstgalaxies; (iv) relate these important properties of the clustergalaxies to quantities such as stellar mass, galaxy morphology, localgalaxy density, and the density of the intra-cluster medium, todetermine which physical processes are responsible for thetransformation of galaxies from late-type to early-type. We will alsosearch for intra-cluster dust which is expected to be produced viastripping 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.
