    • COSMOS ACS I-band Photometry Catalog

    Metadata Updated: April 10, 2026

    COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.\n\nThis is the ACS catalog for the COSMOS survey that has been constructed from 575 ACS pointings. Please see Leauthaud et al. 2006, ApJ, for project and data details.
