This class is an introduction to the modern extragalactic astronomy and cosmology, i.e., the part of astrophysics that deals with the structure and evolution of the universe as a whole, and its major constituents: dark matter, dark energy, galaxies, quasars, large-scale structure, and intergalactic gas.  It will cover the subjects including: relativistic cosmological models and their parameters, extragalactic distance scale, cosmological tests, composition of the universe, dark matter, and dark energy; the hot big bang, cosmic nucleosynthesis, recombination, and cosmic microwave background; formation and evolution of structure in the universe; galaxy clusters, large-scale structure and its evolution; galaxies, their properties and fundamental correlations; formation and evolution of galaxies; star formation history of the universe; quasars and other active galactic nuclei, and their evolution; structure and evolution of the intergalactic medium; diffuse extragalactic backgrounds; the first stars, galaxies, and the reionization era.  It corresponds to the Ay 21 class taught at Caltech.

The professor was able to condense a massive amount of information in a series of short lectures over a relatively brief period of nine weeks. He tried to keep it as concise and "non-mathematical" as possible with most of the information being descriptive and graphical. Equations and small proofs were included but the course did not require you to do any extensive mathematical exercises or derivations. Although, one could if they pleased go to the university website and get the problem sets from there or alternatively purchase one of the proposed textbooks and solve the problems from the relevant chapters. All in all a great course and an excellent explainer (Prof. Djorgovski). Highly recommended if you have an interest in modern cosmology and galactic evolution.
