Abstract / Description of output

One of the major outstanding questions in AGN studies is whether Fanaroff & Riley class I and II (FRI and FRII) radio galaxies are fundamentally discrete classes of object, or simply different manifestations of intrinsically similar objects. This work aims to provide the first direct measurement of the high redshift space density and subsequent cosmic evolution of FRI radio galaxies with the aim of investigating this question. First results, reported here, suggest moderate FRI density enhancements at redshifts of >1.0.
