The Planck mission has the unique capability of finding systematically and on the whole sky the rarest, most luminous high redshift submm sources. These can be lensed objects or proto-groups/clusters of galaxies containing many individual sources forming stars at very high rates. Our full sample of candidates contains about 1 source per 30 sq. deg., and already 3 candidates have been confirmed as interesting high-z sources: one was found to be a proto-group at zvirgul3, based on a SPIRE OT1 pilot project; and 2 others are zvirgul3-4.6 sources already found in the H-ATLAS and around A773. We now propose to use SPIRE to image a larger set of Planck sources to obtain a statistically significant sample of 70 high-z proto-groups and clusters. This will give new insights into the early evolution of galaxies in the highest density regions, improving our understanding of the relationship between the growth of structures and star-formation, and placing constraints on the level of non-Gaussianity within the LCDM model. This program exploits the exceptional synergy and complementarity between Planck and Herschel.

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.
