Introduction to active galaxies

Introduction

Active galaxies provide a prime example of high-energy processes operating in the Universe. This course introduces the evidence for activity from the spectra of some galaxies, and the concept of a compact active galactic nucleus as a unifying model for the observed features of several types of active galaxy. It also develops the key skill of applying arithmetic and simple algebra to solving scientific problems.
