Title: U-band study of the z=2.38 Filament

Abstract: We request 3 nights on the CTIO Blanco 4m with the MOSAIC camera to image the z=2.38 Filament in U-band. The primary goal is to achieve depths in the U filter (26.5 AB) necessary to identify further members of this high redshift structure, using the "BX" method of Steidel et al. (2004) and photometric redshifts. Combined with deep \it Spitzer (IRAC and MIPS 24(mu)m) and near-IR data, we will measure mass, ages, dust content, and SFR throughout this region of early galaxy assembly. Further structure members will also facilitate a robust determination of the weakly-detected filament and void distribution. We will also obtain z'-band imaging in order to provide a full data set for photometric redshifts.
