After studying this course, you should be able to:
- Explain how and why the optical spectrum of an active or starburst galaxy differs from that of a normal galaxy

- Describe briefly the observed features of starburst galaxies and the four main classes of active galaxies (quasars, radio galaxies, Seyfert galaxies and blazars)
- Understand the evidence that indicates the presence of a compact active galactic nucleus (AGN) in active galaxies
