To appreciate that some galaxies emit far more energy at some wavelengths that can be explained simply in terms of ‘starlight’.. To recall the types of active galaxies.. To show an understanding of the mechanism for producing large quantities of radiation from active galaxies.. Anja. von . der. Linden et al., 2007, MNRAS, 379, 867.
