The term Active Galactic Nuclei includes QSOs (Quasi-Stellar Objects), Seyfert galaxies, BL Lac objects and nuclei showing unusual amounts of star formation. South African work has centred on the photometric properties of these objects, both in the optical(UBVRI) and the infrared(JHKL). Photometry has been used to investigate the nature of the relevant

Well before the discovery of quasars, a special class of galaxies was known to harbor unusually powerful nuclei (Seyfert, 1943). Two primary defining characteristics of these active galactic nuclei (AGNs) are an intense point-like nuclear continuum source and strong, broad emission lines, neither of which could arise from ordinary stellar processes ...

These lectures review briefly the spectra and classification of active galactic nuclei (AGN), including quasi-stellar objects (QSOs), and the properties of their ‘host’ galaxies; starbursts (SB) and the possible association between galaxy interactions, SB, and AGN.
