Scientific paper

The NOAO Deep Wide-Field Survey (NDWFS) is a very deep optical and IR (BWRIJHK) imaging survey of 18 square degrees of the sky with the primary goal of studying the evolution of large-scale structure from z 1-4. The survey enables investigation of the formation and evolution of galaxies and the detection of luminous, very distant (z>4), star-forming galaxies and quasars. The images are also being used for weak-lensing studies and to provide information on the optical/IR counterparts to sources detected at other wavelengths. The extensive multi-wavelength observations targeting the NDWFS fields include observations with Chandra (x-rays), GALEX (UV), SIRTF (near, mid, and far IR), the VLA, and Westerbork (radio). I will review the design of the survey, the status of observations (nearing completion with 90% of the data obtained), and initial scientific results (e.g., evolution of clustering of red galaxies and EROs, see also contribution by M. Brown et al. at this meeting; IR properties of FIRST Survey detected radio galaxies in the NDWFS, see contribution by Henderson et al. this meeting). Our research is supported by the National Optical Astronomy Observatory which is operated by the Association of Universities for Research in Astronomy, Inc. (AURA) under cooperative agreement with the National Science Foundation.
