Massive galaxies provide the key to understanding galaxy formation in the early universe. The best tool for identifying the most massive galaxies is strong radio emission, which signals the presence of an active nucleus powered by a supermassive black hole. Their mere existence at redshifts z>3, when the universe was <2 gigayears old, challenges current theories for galaxy formation, but relatively few such objects are known. Identifying such systems is commonly done by targetting objects with steep radio spectral slopes, and the Phoenix Deep Survey has recently identified 9 compact radio sources with particularly extreme spectral slopes. These are either candidate high redshift radio galaxies, or possibly some other novel class of source. We propose to obtain 2.4 GHz and 4.8 GHz imaging of these objects to refine the spectral index measurements and identify or rule out any possible extended radio emission.
