THE PHOENIX DEEP SURVEY - 1.4-GHZ SOURCE COUNTS

We present the first results from the Phoenix Deep Survey, a multiwave length survey of a 2 degrees diameter region. Observations in the radi o continuum at 1.4 GHz carried out with the Australia Telescope Compac t Array are described. The catalogue of over 1000 radio sources compil ed from these observations is analysed, and the source counts are pres ented. We model the observational source counts using a two-population model and published luminosity functions for these populations. Upon invoking luminosity and density evolution, we find that a luminosity e volution model best fits the radio observations, consistent with earli er work. The redshift distribution of the two galaxy populations inves tigated is also modelled and discussed.
