The COSMOS Archive serves data taken for the
Cosmic Evolution Survey
(
COSMOS)
project, using IRSA's general search service,
Atlas.
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. The COSMOS
survey involves almost 100 scientists in a
dozen countries. The Spitzer observations of the COSMOS
field (
S-COSMOS
Legacy Project) have been integrated into
the COSMOS archive. S-COSMOS images are incorporated in the search
results using the form below. The COSMOS and S-COSMOS
photometry catalogs can be accessed using IRSA's
General Catalog Search Service,
Gator.
Use the search form below to request data.
Search results will show ACS, VLA, IRAC, MIPS, GALEX, NICMOS,
WFPC and XMM
cutout images of the requested search size;
Subaru, KPNO, CFHT and SDSS
images that overlap the search box; and VLA
sources which fall within that region.
Use
Gator to perform advanced searching on
COSMOS and S-COSMOS
photometry catalogs.
Also available are image "
cutouts" using IRSA's
Cutouts Service, which is a general tool to create single or multiple small FITS (and JPEGs) image cutouts of datasets archived at IRSA.
