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 µJy, 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.
