About this Image

The Cosmic Evolution Survey (COSMOS) is a pan-chromatics (X-ray to mm) observational project to perform a detailed study of galaxy and super-massive black hole evolution through cosmic times, with particular emphasis on the influence of environment and large scale structure. This VLA Large Project is the largest radio deep field at this depth and angular resolution. It provides about 3500 compact and extended radio surces allowing the study of the dust-obscured star formation history of galaxies and the evolution of active galactic nuclei through cosmic history. The insets to the right and the bottom show radio galaxies that have been detected in the 1.4 by 1.4 degree image.

Technical Caption	At radio wavelengths, the VLA-COSMOS Survey uses NRAO's Very Large Array (VLA) to conduct state-of-the-art (~ 1.5" resolution), deep (1sigma ~ 10 microJy), wide-field imaging at 1.4 GHz continuum of the COSMOS 2 square degree deep field. A total of 250 hr in A array and 25hr in C array was spent to observe the 23 pointing which are required to cover the COSMOS field.
