Abstract

The VLA-COSMOS Large Project is described and its scientific objective is discussed. We present a catalog of ∼3600 radio sources found in the 2 deg 2 COSMOS field at 1.4 GHz. The observations in the VLA A and C configuration resulted in a resolution of 1.5″ × 1.4″ and a mean rms noise of ∼10.5 (15) μJy beam -1 in the central 1 (2) deg 2. Eighty radio sources are clearly extended consisting of multiple components, and most of them appear to be double-lobed radio galaxies. The astrometry of the catalog has been thoroughly tested, and the uncertainty in the relative and absolute astrometry are 130 and <55 mas, respectively.
