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.

Phenomenology of Active Galactic Nuclei
1990Active galactic nuclei constitute a somewhat vaguely defined class of objects. It is very well possible that most galaxies have nuclei and that these are active in the sense that there is an energy source in addition to the thermonuclear sources inside the constituent stars.
