Leerdoelen At the end of the course, the student is able to:

1. Describe the main type of active nuclei, their structure and the observable characteristics at different wavelengths
2. Formulate basic models to describe their source of energy
3. Explain the emission mechanisms related to the black hole and their impact on the host galaxy
4. Solve problems related to the basic properties of the AGN at different wavelengths
5. Discuss critically recent observations and models (as published in the literature)
Omschrijving During the life of a galaxy, the central black-hole can go through phases of "activity" releasing huge amount of energy that cannot be originated by stars. Galaxies in this phase are called Active Galactic Nuclei (AGN). A variety of phenomena can be observed in AGN. Furthermore, the energy released by the active nucleus is believed to have a major impact on the evolution of the host galaxy. How to recognize and explain the AGN phenomena and the evidence for the interplay between the AGN and the surrounding interstellar and intergalactic medium are the subject of this course.

The student will gain a general overview of the field of Active Galactic Nuclei and will be introduced to several topics in this field, such as Seyfert galaxies, radio galaxies, quasars and related AGN (active galactic nuclei). Physics and energetics of continuum and line emission. Host galaxies and environments. Relation to starburst phenomena/galaxies. Luminosity functions, cosmic evolution. Quasars as cosmological probes. Unification theories. Feedback effects.

"An Introduction to Active Galactic Nuclei"
by Bradley M. Peterson
Entreevoorwaarden The course unit assumes prior knowledge acquired from a course on Physics of Galaxies and Radiative Processes (or equivalent).
Opmerkingen The course exam will consist of two parts: a written exam, homework (two reports) and a final oral presentation (of paper selected among a list provided). The written exam is closed-book and will consist of open questions and some calculations. The evaluation will be based on a points scheme with points assigned to each question.
The student is expected to follow at least 70% of the course in order to be admitted to the exam.
