Description

This course provides the student with a background in modern cosmology and exoplanets. The course presents a physical description of the structure and formation of galaxies, clusters and large-scale structure in an expanding Universe dominated by dark matter and dark energy. The discovery techniques of exoplanets are explained, as are the methods that can be used to characterise their bulk properties and atmospheres. Also included are the evolution of planetary systems and the mechanisms involved.

Learning Outcomes

1. Outline and discuss the structure and kinematics of the Milky Way Galaxy, know properties of supermassive black holes and Sgr A*
2. Understand the formation and merger of galaxies and be able to compare different types of Galaxies
3. Describe categories of active galaxies and models for emission properties
4. Discuss the contents, history and origin of the Universe, know the relation between the contents of the Universe and its evolution.
5. Discuss Inflation and nucleosynthesis in the very early Universe, formation of structure
6. Discuss the origin of the cosmic microwave background
7. Discuss properties of the intergalactic medium
