Schedule, syllabus and examination date

Choose semester

Course content

The first part of the course treats galaxies, active galactic nuclei, and galaxy clusters. In the second part theories for the formation of structures in the Universe and methods for observing them are discussed.

Learning outcome

After completing this course you should be able to:

  • Describe the different types of galaxies and their physical properties. You should know how the rotation curve of the Milky Way is measured, and treat models for galactic stellar populations and dark matter distributions quantitatively.
  • Treat models for clusters of galaxies and methods for determining their masses and dark matter distributions.
  • Apply Newtonian perturbation theory and understand the evolution of structures in the linear regime, and the statistical methods for describing them.
  • Understand the spherical collapse model for structure formation, both qualitatively and quantitatively.
  • Describe how gravitational lenses can be used as a tool to study structures in the Universe, and apply them quantitatively in idealized situations.

Admission
