AST3220 ¨C Cosmology I

Course content

This course provides an introduction to cosmological models and important eras in the history of the universe, including inflation and the generation of inhomogeneities by quantum fluctuations.

Learning outcome

After completing?this course, you will be able to:

• define the principles and equations that are the foundation of models of the universe in the general theory of relativity.

• explain important cosmological observations and how they are used to determine the characteristics of the Universe.

• describe, qualitatively and quantitatively, important eras in the history of the universe: inflationary phase, radiation dominated phase with disengagement of dark matter and neutrinos, nucleosynthesis, matter dominated universe, recombination and the formation of cosmic microwave background radiation.

• describe how quantum fluctuations during inflation are the source of density fluctuations and gravitational waves.
