Description We propose an experiment to search for signatures of rapid growth of galaxies and AGNs in a sample of three z>2 proto-clusters. These environments are exceptionally rare, pre-virialised regions corresponding to peaks in the matter density field, located at the nodes of large-scale (>10-Mpc) filamentary structures. They are the best candidates for the progenitors of the most massive clusters of galaxies (~10^15-Msun) today. We pay special attention to an unusual class of object, preferentially located in proto-clusters: Lyman alpha blobs (LABs) - 100-kpc scale luminous emission-line gas nebulae. Some LABs show signatures of recent galaxy-galaxy mergers-interactions, are often host to luminous continuum sources, and many have evidence of gas inflows-outflows in their emission-line morphology. A significant fraction of LABs have embedded galaxies detected at X-ray, mid-infrared, and-or sub-mm wavelengths, suggesting possible rapid growths of the galaxies and AGNs in proto-cluster regions. Are the proto-cluster systems more obscured than galaxies in the field? Are the protocluster systems growing more rapidly? By mapping these proto-clusters with SPIRE, we will: (1) measure SFRs in sub-mm (rest-frame FIR) for the galaxies and AGNs in the proto-clusters, and determine how much star formation is obscured (when compared to UV estimate) and (2) determine SSFRs for the galaxies and AGNs in the proto-clusters, and see how they compare to field galaxies at z=2-3. This program will deliver fundamental information on the growth of galaxies and super-massive black holes in the densest regions of the Universe at high-redshift, and provide valuable insight into the astrophysical processes that establish the trends linking galaxy properties and their environments.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
