ASTR6000: Cosmology (Spring 2026)

Author

Preface

This book contains lecture materials for ASTR6000: Cosmology, taught in Spring 2026.

Acknowledgements

I have drawn heavily from two primary textbooks for this class:

A Course in Cosmology by Dragan Huterer
Cosmology by Daniel Baumann

There are many other excellent textbooks, not to mention review articles etc. As we go along, I will try to maintain a running bibliography.

This is a good place to acknowledge my debt to many sources for this class. A large portion of this class will follow the two textbooks and in many, many cases, my presentation and problem sets will directly borrow from them. Citing these sources as I proceed would be quickly tedious, but I will try to point to the relevant sections in the textbooks as we go along.

In cases where I borrow an argument from a different source, I will add this both to the bibliography and class notes.
