Class description: syllabus
This is the course webpage for the Spring 2022 lectures of "Physical Cosmology" offered by Uni Zurich. In this course (formerly known as Theoretical Cosmology), we study the history of our universe on large scales. We first discuss key cosmological observations that led to our standard model of cosmology, and we study in detail the origin and the evolution of the Universe such as inflation, big bang nucleosynthesis, and cosmic microwave background anisotropies. In the second part we learn (relativistic) perturbation theory and apply it to initial conditions, large-scale structure and weak gravitational lensing. The course and exercise classes will be presented in English.
The lectures will be held separately from ETH this year. A different class under the same name will be taught by a different lecturer at ETH.

Lectures by: Prof. Dr. Jaiyul Yoo (jyoo physik.uzh.ch)

Teaching assistants: Matteo Magi (matteo.magi uzh.ch) and Sandra Baumgartner (sandra.baumgartner uzh.ch)

Prerequisites: Basic knowledge of general relativity is required

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 - Inhomogeneous Universe
  1. Newtonian Perturbation Theory
  2. Probes of Inhomogeneities
  3. Relativistic Perturbation Theory
  4. Standard Inflationary Models
  5. Weak gravitational lensing
  6. Cosmic microwave background anisotropies (time permitted)
