Galaxy evolution and AGN growth in the early universe are believed to be strongly driven by merging (hierarchical growth) and galaxy dynamical interactions. Thus, a full exploration of the environmental influences is absolutely essential to understanding this early evolution. The Cosmic Evolution Survey (COSMOS; Scoville et al. in Astrophys. J. Suppl. Ser. 172:1, 2007) is specifically designed to probe the correlated coevolution of galaxies, star formation, active galactic nuclei (AGN) and dark matter (DM) large-scale structures (LSS) over the redshift range z > 0.5–3. The survey includes multi-wavelength imaging and spectroscopy from X-ray to radio wavelengths covering a 2 deg^2 equatorial field. Given the very high sensitivity and resolution of these datasets, COSMOS also provide unprecedented samples of objects at z > 3 and will be a fundamental resource for future cosmology studies. I reviewthe characteristics of the COSMOS survey and showexciting initial results mapping large scale structures in galaxies and dark matter.
