The cosmic evolution survey – Cosmos

Abstract

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.
