. ATLAS is a project to image seven square degrees of sky, in two fields (CDF-S and ELAIS-S1), at radio wavelengths, to an rms of about 15 Jy, making it the widest deep radio survey aver attempted. The fields are chosen to cover the Spitzer Wide-Area IR Extragalactic Survey (SWIRE), and the radio images cut through the dust, to trace the cosmic history of AGN and star-forming galaxies.
