'Large Scale Structure and Extreme Star formation at z>4 '

Theory expects and statistical observations confirm that large scale structure has a significant role in the formation and evolution of the first galaxies. However, the influence of large scale structure at high redshift (z>4) remains largely un-quantified due to the spacial extent of structures at these redshifts and the faint fluxes of the galaxies that populate them. Using imaging from the COSMOS survey combined with deep spectroscopy from Keck covering a 0.5x1 degree region we begin to quantify the role of large scale structure. We show the typical structure extends over 10's of arc-minutes and that Quasars and Extreme-Starbursts (SMGs) appear to preferentially populate these structures. We also link the members of these proto-clusters to their likely decedents at z~2.
