Here we review the characteristics of the HST imaging with the Advanced Camera for Surveys (ACS) and parallel observations with NICMOS and WFPC2. A square field (1.8 deg2) has been imaged with single-orbit ACS I-band F814W exposures with 50% completeness for sources 0.5" in diameter at IAB=26.0 mag. The ACS is a key part of the COSMOS survey, providing very high sensitivity and high-resolution (0.09" FWHM and 0.05" pixels) imaging and detecting a million objects. These images yield resolved morphologies for several hundred thousand galaxies. The small HST PSF also provides greatly enhanced sensitivity for weak-lensing investigations of the dark matter distribution. Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555. | Free Keywords: | Cosmology: Observations; Cosmology: Dark Matter; Galaxies: Evolution; Galaxies: Formation; Cosmology: Large-Scale Structure of Universe; Surveys | External Publication Status: | published | Document Type: | Article |
