Description
Target group 
Master’s Programme in Particle Physics and Astrophysical Sciences is responsible for the course.
Modules where the course belong to:
 PAP300 Advanced Studies in Particle Physics and Astrophysical Sciences
Optional for:
 Study Track in Particle Physics and Cosmology
 TCM300 Advanced Studies in Theoretical and Computational Methods
The course is available to students from other degree programmes. 
Timing 
Recommended time for completion is after FYS2081 Cosmology I. First year of Master's level studies.
Lectured every year. The course will be offered in the autumn term, in II period. 
Learning outcomes 
 You will learn to calculate the primordial perturbations produced by a given inflation model.
 You will understand how these primordial perturbations develop into the present largescale structure of the universe.
 You will understand how these perturbations affect the anisotropy of the cosmic microwave background and how the latter can be used to determine the values of the cosmological parameters.

Completion methods 
Homework problems and course exam
