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
explain how and why the broadband 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
explain why an AGN should emit broad lines, narrow forbidden lines and continuous radiation.
