### Description

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.

FYS2081 Cosmology I, FYS2010 Mathematical Methods Ia, FYS2011 Mathematical Methods Ib (Fourier series), or similar background

PAP335 General Relativity can be taken either before or after this course

- 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 large-scale 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.

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.

- Cosmological inflation in the early universe as explanation for the initial conditions of the Big Bang

- Inflation models and how inflation generates primordial perturbations (density fluctuation sand gravitational waves)

- Structure formation: how primordial perturbations develop into the present large-scale structure: Newtonian first-order perturbation theory; a little bit of relativistic perturbation theory

- Cosmic microwave background anisotropy; its description and physics; connection to primordial perturbations and cosmological parameters
