Description
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 90 cm Very Large Array imaging of the COSMOS field comprises a circular area of 3.14 square degrees at 8.0 arcsec by 6.0 arcsec angular resolution with an average rms of 0.5 mJy/beam. The extracted catalogue contains 182 sources (down to 5.5 sigma), 30 of which are multicomponent sources.
