Abstract
The era spanning 0 < z ≲ 1 is witness to strong evolution of star-formation in galaxies, evidenced by a decline of almost an order of magnitude in the space density of galaxy star-formation rates. Understanding galaxy evolution over this significant fraction of the age of the Universe is an extraordinarily complex undertaking. Investigation of this cosmologically significant era in a coherent fashion is complicated by the heterogeneous nature of the many surveys required to probe the full redshift range. The unknown extent of dust obscuration at different redshifts, extremely important for studies of star-formation, also adds to the complexity. These difficulties are being addressed by the Phoenix Deep Survey, an ongoing very sensitive radio survey. A homogeneous radio-selected catalogue of over 2000 sources reaching flux densities as faint as 50 mu Jy has been compiled.
