Title: U- and I-band imaging of the CDF-S in support of the GOODS SIRTF Legacy and HST Treasury programs

Abstract: We request time for deep U- and I-band imaging of the Chandra Deep Field South (CDF-S) as part of the Great Observatories Origins Deep Survey (GOODS). GOODS is a campaign of multiwavelength observations from \it SIRTF, \it HST, \it Chandra, \it XMM- Newton, NOAO, ESO, and radio facilities, to gather a public data resource for studying galaxy and AGN evolution, cosmological expansion, and the extragalactic background light. Deep optical and infrared images are essential to complement the space-based GOODS data, providing spectral energy distributions and photometric redshift estimates for galaxies and AGN, and enabling target selection for spectroscopy with Gemini and VLT. The CTIO data will be used with deep BVR images from the Wide Field Imager (WFI) on the ESO 2.2m telescope, which cannot reach the required limits at U or I. The U observations are especially critical for Lyman break galaxy selection at z ~ 3, because the \it HST/ACS WFC is UV-blind. The CTIO U- band data will be the deepest available, and the only suitable counterpart to the KPNO 4m U imaging of the northern GOODS field (HDF- N), due to the lack of wide-field, U-sensitive imagers on any other southern, large-aperture telescope. As with all data from GOODS, the reduced CTIO images will be available to the research community. This program was approved for 2001B and 2002B, but has not yet been completed due to weather and technical problems (see text).
