Description We propose an experiment to investigate the evolution of the most massive galaxies that reside in the cores of massive clusters today. We aim to catch their progenitors - gas-rich, intensely starbursting galaxies - in the act of accretion onto massive halos at z~1. Our survey is unique because we will map a super-cluster environment that is in the throes of a spectacular 3-way merger, allowing us to examine the astrophysics of galaxy evolution during a key stage of the hierarchical build-up of large scale structure. Our target - RCS 2319 - is a system of three ~5x10^14 M_Sun galaxy clusters at z=0.9 separated by just 3 Mpc. RCS 2319 is the progenitor of a >10^15 M_Sun cluster, and the ideal target to examine the complex relationship between the formation of massive galaxies and the dense, dynamic environments they inhabit. We will obtain a deep map of RCS 2319 with SPIRE, covering a projected extent of 14x14 Mpc, including the full range of sub-environments from the dense cores out to the group-scale and filamentary structure in the super-cluster outskirts. Our goals are to (i) identify ULIRG-class (>10^12 L_Sun) cluster members and investigate their properties in the context of the super-cluster environment; and (ii) calculate the cross-power spectrum of FIR emission with galaxy surface density, allowing us to search for statistical correlations between obscured star formation and environment beyond the confusion limit.

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.
