"SCOSMOS: The MIPS Deep Survey of the COSMOS 2-Sq Degree Field"

Principal Investigator: David Sanders (University of Hawaii)

Total Observatory Time: 396.2 hours

We propose a deep imaging survey with the Spitzer MIPS detectors to observe the full HST-COSMOS 2-sqdeg field. COSMOS is an approved HST Treasury program that is specifically designed to probe the coupled formation and evolution of galaxies and large-scale structure on scales up to 2x10^14 M_sun during the formation era of galaxies, AGN, and clusters (z~0.5-2.5). The Spitzer observations proposed here are needed to complement our Cycle2 IRAC-deep imaging of the full COSMOS field, plus the multi-wavelength images of the COSMOS field from X-ray to radio, including very deep multi-band images (20 filters) from the Subaru telescope. The COSMOS field is also currently the target of a massive spectroscopic redshift survey with the VLT (50,000 spectra down to I~25). The MIPS-deep data are critical for deriving star formation rates, and AGN activity of galaxies and their dependence on morphological properties and clustering environment over the last 90% of the cosmic history. For the first time, COSMOS will yield statistics of high-redshift sources with greatly reduced cosmic variance, and enable the discovery and characterization of relatively rare objects. COSMOS is thus the necessary complement to deeper but much smaller (>100x) surveys (GOODS and UDF). As part of our Legacy status, our team will immediately release our Spitzer observations, along with our other multi-wavelength COSMOS data and source catalogs, to the astronomical community to ensure maximum scientific return from this survey.
