FYS9130 – Cosmological physics

Course content

Einstein-Hilbert action and quantum fields in curved spacetimes. Inflation and reheating. Quantum fields at finite temperature. Standard model in the early universe. The Boltzmann equation. Cosmological phase transitions. Baryogenesis. Nucleosynthesis and recombination. Microwave background radiation. Quantum fluctuations and the primordial spectrum. Cosmological pertubation theory.

Learning outcome

The course is aimed at master and PhD students working in cosmology and elementary particle physics. It gives a survey of current approaches to and understanding of the physics of the early universe based on the standard model of particle physics and extension thereof. The level of the lectures will be the same as in the modern research literature.


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.
