[48.05] A Spitzer Program to Observe the NDWFS Field in Bootes

B.T. Soifer (SSC & Physics,Math & Astronomy, Caltech), Spitzer/NOAO Team

A Spitzer/MIPS survey at 24, 70 and 160 microns has been conducted of the NOAO Deep Wide-Field Survey (NDWFS) Field in Bootes in early February 2004 as a major component of the IRS & MIPS teams GTO program. The Survey reached a sensitivity level for detections of ~0.1-0.2 mJy at 24 microns, with correspondingly higher flux density levels at 70 and 160 microns. The positions of the 24 microns sources are excellent, generally being within <0.4" of an optical counterpart on the NDWFS images. More than 95% of the sources brighter than 0.75mJy at 24 microns have optical counterparts in the NDWFS images.

The goals of the survey are to understand the population of galaxies that emit strongly in the infrared in the distant universe. To achieve these ends, follow-on observations have been scheduled with Spitzer/IRS to obtain spectra of 24 micron sources without optical counterparts, and optical spectra have been obtained on the Keck telescopes of the sources with faint optical counterparts. Early results from this survey will be described.

The Spitzer Space Telescope is operated by JPL/Caltech under NASA Contract 1407. The NDWFS is supported by NOAO, which is operated by AURA, Inc., under a cooperative agreement with the National Science Foundation.
