Course content

Relativistic cosmology: basics of GR, Friedmann's equations, FRW- and de Sitter universes. The early universe: inflation, Big Bang nucleosynthesis, the formation of the cosmic microwave background radiation. Structure formation: evolution of cosmological density perturbations, formation of large-scale structure in the Universe, and fluctuations in the cosmic microwave background radiation.

Learning outcome

You will develop an understanding of modern physical cosmology and methods for solving cosmological problems. The course will give you the necessary background for choosing a topic for a master degree thesis in cosmology.


PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.

If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.

PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.
