Galaxies and Cosmology, ASTA33, 7.5 hp

The course is given the second period of each fall term

The course is given in Swedish or English

Description

The course takes its starting point in how we can understand how the Universe formed and evolved through the study of its contents and in particular the study of galaxies. Galaxies are mainly made of dark matter, but the  light we observe comes from the stars, the baryonic-bright matter. Through the study of the stellar light  emitted by the galaxies we can learn about the universe itself. Through these studies you naturally encounter Einstein's general theory of relativity and the Friedmann equations and their solution. We will go through the observational evidence for dark energy in detail. Dark energy is today thought to govern the evolution of the universe.
