Length of Course: 1 semester
Aims of the Course:
Understanding of fundamental concepts and physical radiation mechanisms for active galactic nuclei
Like Seyfert-galaxies, QSOs, quasars, and violently variable objects.
Contents of the Course:
The lecture introduces to basic aspects of active galactic nuclei:
Types of sources HII-galaxies, LINERs, Seyfert I, Seyfert II, QSO I , QSO II, BLLac /OVV-sources
Structure of an active nucleus: Broad line region (BLR), Narrow line region (NLR) and extended narrow line region (ionization cone).
Forbidden and permitted line transitions as density and temperature probes
Continuum emission processes: free-free and synchrotron radiation
Radio galaxies, jets and lobes as well as super luminal motion in jets.
