Description
Active galaxies provide a prime example of high energy processes operating in the Universe. This free course gives an overview of active galaxies, including the supermassive black holes that power the engines at their centres, and the emission processes by which we detect and study them. It also gives practice in mathematical techniques for analysing data and theoretical models.
Course learning outcomes
After studying this course, you should be able to:
- Recognise the terminology which is used to describe the properties and behaviour of active galactic nuclei (AGN)
- Manipulate numbers, algebraic symbols and mathematical functions in equations.
