AST3220 – Cosmology I
Course description
Course content
This course provides an introduction to cosmological models, 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.
- you will?be?able to explain important cosmological observations and how they are used to determine the characteristics of the Universe.
- you will know how?to 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.
- you can?describe how quantum fluctuations during inflation are the source of density fluctuations and gravitational waves.
