What is Co-evolution of AGN and Star-forming Galaxies in the Australia Telescope Large Area Survey about?

ATLAS (Australia Telescope Large Area Survey) is a wide deep radio survey which is distinguished by its comprehensive multi-wavelength approach. ATLAS is creating a large dataset of radio-selected galaxies for studying the evolution and inter-relationship of star-forming and active galaxies. Although the project is far from complete, we are already starting to answer some of these questions, and have stumbled across three surprises along the way: * FRI/FRII radio-loud AGN embedded within spiral galaxies, * radio-bright AGN which are unexpectedly faint in the infrared, and which may be at high redshift * IR-luminous radio-quiet AGN which are partly responsible for the wide variations in reported values of the radio-infrared ratio These and other observations suggest that the AGN activity and star formation become increasingly inter-dependent at high redshifts.
