Scientific paper

Recent observations of two radio galaxies, 3C277.3 and Centaurus A, reveal the coexistence of emission line filaments and the extended radio-emitting regions. Coincident associations of young stars are also found in Cen A. A model is proposed here that can account for the presence of both emission line regions and young stars as arising from the entrainment of interstellar matter by the outflowing gas which powers the radio source. Late evolution of the young stars may provide a significant fraction of the in situ energy injection required for the radio sources.
