Description

This module focuses on a general understanding of the properties of galaxies and the intergalactic medium, along with the different observational techniques used to study them.

Learning Outcomes

1. Interpret basic astronomical data, extract relevant parameters
2. Assess the most appropriate observational techniques for variety of systems.
3. Explain galactic rotation and discuss the impact of dark-matter on rotation curves.
4. Describe the different building blocks of galaxies
5. Summarise the formation processes of galaxies, and their impact on observables.
6. Understand the role of magnetic fields in different cosmic environments
7. Discuss the nature of the intergalactic medium on different cosmic scales and times
