Title: Optical/IR Survey of Large-Scale Structures in The Bright Ages'' (z=1- 3)

Abstract: The apparent peak of the global star formation rate in the Universe, between z=1 and z=3, has not been well sampled. We will use the powerful combination of BVRI and JK photometry to produce a K-magnitude selected sample of faint galaxies likely to lie in this range, for followup LRIS spectroscopy at the Keck observatory. In addition to determining \it when most star formation occurred, we will determine \it where it was most vigorous, by specially targeting some of the highest-density regions known in the young Universe. The BVRI data acquisition is well underway at Lick observatory, but infrared data acquisition has been much slower thanks to the small field size of the UCLA IR camera (3'x3') so far available. The field of view of Flamingos camera on the 4-m KPNO telescope (10'x10') perfectly matches that of our optical data, which is necessary to survey these fields properly and for a meaningful search for high redshift structure. We will require only a single night for! ! this purpose.
