In this class, we will discuss the physics and astrophysics of the late Universe, building on the discussion of the early Universe in Physics PHYSICS 362. In particular, we will explore the dynamics, structure, and evolution of the Universe starting from nucleosynthesis and ending several billion years later (covering recombination, reionization, and the formation of the first galaxies along the way). We will pay special attention to the mathematics underlying key observations that have been instrumental in developing the standard cosmological model, such as galaxy clustering and the cosmic microwave background perturbations, as well as numerical tools used to compare theory and data. Undergraduate exposure to general relativity and cosmology at the level of Physics PHYSICS 262 and PHYSICS 161/PHYSICS 261 will be helpful but is not essential. Whilst this course will involve material covered in Physics PHYSICS 362, the key points will be summarized when needed.
