Testing models of radio source space density evolution with the SUMSS survey

We present the population data as predicted by our space density analysis at the SUMSS frequency of 843 MHz. This data demonstrates the potential of the SUMSS survey to trace in detail the change-over in radio source populations from `radio monsters' at high flux densities to a local starbursting population at the survey limit. The exact form of the observed change-over will be used to refine our models of radio source evolution
