Class description: This is the course webpage for the Spring 18 lectures of "Theoretical Astrophysics and Cosmology" offered jointly by ETH and Uni Zurich. This course is intended for Master students and qualifies as a Theoretical Core Course. It is the second of a two course series which starts with "General Relativity" and continues in the spring with "Theoretical Astrophysics and Cosmology". The course and exercise classes will be presented in English.

Lectures by: Prof. Dr. Lucio Mayer and Prof. Dr. Jaiyul Yoo

Teaching Assistants: Fulvio Scaccabarozzi and Nastassia Grimm

Prerequisites: General Relativity

About the Course The course will focus on applying General Relativity to Cosmology as well as developing the modern theory of structure formation in a cold dark matter Universe. The syllabus consists of the following topics:

Part I - The Unperturbed State of the Universe
1. Introduction: dynamics of expanding Universe and its matter/energy content
2. The FRW metric and Friedmann equations
3. The Thermal History of the Universe (Hot Big Bang model)
4. Decoupling and Thermodynamics of relic particles
5. Nucleosynthesis and Recombination
6. Introduction to Inflationary Theory

Part II - The Perturbed State of the Universe
1. Newtonian Perturbation Theory
2. Probes of Inhomogeneities
3. Relativistic Perturbation Theory
4. Standard Inflationary Models
5. Perturbed Boltzmann equation
6. CMB Anisotropies
7. Weak Lensing and CMB Polarization

Advanced Topics of Theoretical Cosmology

The course "Advanced Topis of Theoretical Cosmology" is an extension of "Theoretical Astrophysics and Cosmology" and is given by Prof. Dr. Jaiyul Yoo.
The lectures take two hours (10am-noon), every day for two weeks, from 3 September to 14 September 2018.
It is listed in the ETH course catalogue of the Fall Semester 2018, and ETH students must book this block course directly at UZH.
