Scientific paper

The NOAO Deep Wide-Field Survey (NDWFS), a deep optical (BWRI) and near IR imaging survey of 18 square degrees of the sky, has the primary goal of studying the evolution of large-scale structure between redshift 4 to 1. The survey also enables the investigation of the formation, assembly and evolution of galaxies and the detection of powerful quasars and star-forming galaxies, including obscured examples of these populations. The 9.3 square degree Boötes sub-field of the survey is of particular interest because of the extensive multi-wavelength observations now publicly available. These include imaging with Chandra (X-rays), GALEX (UV), Spitzer (near, mid, and far IR), the VLA, and Westerbork (radio). Selected science results based primarily on the optical and near-IR imaging data sets will be highlighted. For example, we have recently used the galaxy luminosity and correlation functions to trace the assembly history of red galaxies since z=1. The stellar mass contained within the red galaxy population doubles between z=1 and z=0, as blue star-forming galaxies are transformed into red galaxies. We find there is ongoing assembly of the most massive red galaxies at z<1, albeit at a rate that does not lead to rapid growth of red galaxy stellar masses.
