COSMOS 2□∘ Survey


The Cosmic Evolution Survey (COSMOS) will provide complete multi-wavelength imaging and spectroscopy of a 2□∘ equatorial field aimed at sampling the full range of cosmological environments from voids to massive clusters to understand the coupled evolution of dark matter, luminous galaxies and clusters and AGN in the epoch of maximum formation activity from z = 0.5 to 3. The COSMOS survey has several major primary components: 1) HST-ACS imaging covering the entire field in I-band (8100Å); 2) ground-based broadband imaging (Subaru, NOAO and CFHT) providing photometric redshifts (typical accuracy 10%); 3) low resolution optical spectra (R = 200 with VLT-VIMOS) for 90,000 galaxies with I < 25 mag. Over 60 astronomers from Europe, North America and Japan are actively involved in COSMOS multi-λ observations and science.
