The Cosmic Evolution Survey - COSMOS


The Cosmic Evolution Survey (COSMOS) is designed to probe the correlated evolution of galaxies, star formation, active galactic nuclei (AGN) and dark matter (DM) with large-scale structure (LSS) over the redshift range z >0.5 to 3. The survey includes multi-wavelength imaging and spectroscopy from X-ray to radio wavelengths covering a 2 square degree area, including HST imaging of the entire field. Given the very high sensitivity and resolution of these datasets, COSMOS will also provide unprecedented samples of objects at z >3. Here I provide a brief overview of the survey strategy, the characteristics of the major COSMOS datasets, and summarize the science goals.

First, it is pleasure to acknowledgement the wonderful planning of the LOC and SOC which has made this meeting possible; and secondly it is a profound pleasure to acknowledge the enormous and diverse contributions of Professor Sofue to our understanding of galactic structure and evolution. The major COSMOS datasets become publicly available in staged releases (following calibration and validation) through the web site for IPAC/IRSA: http://irsa.ipac.caltech.edu/data/COSMOS/ I gratefully acknowledge the contributions of the entire COSMOS collaboration consisting of more than 70 scientists. The HST COSMOS Treasury program was supported through NASA grant HST-GO-09822.
