This course is an introduction to Cosmology. We follow the course book quite closely and first develop the basic description within Big Bang theory and general relativity to grasp the Friedmann equations required to calculate the evolution of the universe. We also target specific epochs in the universe, from early time Big Bang Nucleosynthesis to the Recombination era which released the Cosmic Microwave background. Inflation is mentioned rather briefly.
