"Observational Cosmology", by Stephen Serjeant (Cambridge U. Pr. 2010), ISBN-10: 0521157153, ISBN-13: 978-0521157155 http://www.amazon.com/Observational-Cosmology-Stephen-Serjeant/dp/0521157153/ [Rather light on theory and calculation, but very up-to-date, comprehensive, well explained and well illustrated in full color].

To supplement the lack of equations in Serjeant, we recommend that you choose one of the following, depending on your interests: A. If your interests are mainly on CMB data analysis: Scott Dodelson, "Modern Cosmology", 2nd Ed (2003), ISBN-10 0122191412 http://www.amazon.com/Modern-Cosmology-Scott-Dodelson/dp/0122191412 Errata at http://home.fnal.gov/~dodelson/errata.html This has a very clear and comprehensive discussion of linear perturbations and their coupling to the radiation that produce CMB fluctuations. It does not mention the existence of galaxies. B. If your interests include not just the CMB, but also the fundamental physics, and the (beyond-the-standard model) origin of fluctuations,: Viatcheslav Mukhanov, "Physical Foundations of Cosmology" (Cambridge U. Pr, 2005) ISBN-10 0521563984 http://www.amazon.com/Physical-Foundations-Cosmology-Viatcheslav-Mukhanov/dp/0521563984 Like Dodelson, does not mention observations, galaxies, quasars, and other such minor details. Also beware of typos/errors (e.g. Problem 1.1 is wrong!). Recommended for physicists and the budding theorist. C. If your interests are mainly in the nonlinear `mudwrestling' phase of the growth of structure, i.e. the assembly of galaxies, black holes, etc: Houjun Mo, Frank van den Bosch and Simon White, "Galaxy Formation and Evolution" (Cambridge U. Pr, 2010), ISBN-10 0521857937 http://www.amazon.com/Galaxy-Formation-Evolution-Houjun-Mo/dp/0521857937

There will be approximately weekly homework sets due in class on Fridays, a term paper (due June 1) and a closed-book final exam. Your grade will be a mostly monotonic function of g = [0.5(sum of homework scores) + 0.2(score of term paper) + 0.3(score on final exam)]. LATE HOMEWORK POLICY: Homework extensions of up to 24 hours can be granted by the instructors or the TA. Longer extensions can only be approved by Sterl. No late homework will be accepted unless one of these prior arrangements has been made. Unapproved late homework will not be graded. COLLABORATION POLICY: In working the homework sets, you may consult your own class notes (which must be written in your own hand from lecture or those of another student; they may not be xerox or scanned copies), and any textbooks required or recommended for this class or any other reference books you find helpful (but please state which you use, if you do use books which are not the texts). You may also use calculator or a computer to do numeric and symbolic calculations, or as a word processor. At no stage may you look at solutions to the problems you might find on friend's desks, on websites, filing cabinets, ftp sites, etc. You may not trade equations, graphs, or look at other people's solution sets from this or any prior year or similar courses at other universities. During the closed-book final, you may not consult any texts, computers or people. You may use a calculator. Collaboration on the homework is LIMITED to getting unstuck. You have to do the homework all by yourself. You may consult books and published papers, but not old assignments or those of other students. First try every homework problem BY YOURSELF without discussing it with anyone. If you get stuck, you can TALK about the homework with the TA or your fellow students, but all exchanges of information must be aural and general in nature (i.e. "Did you remember to include Comptonisation" is ok. "The right answer is V k squared over pi squared" is NOT ok). After any discussion with others, you must write up your own homework by yourself, without reference to anyone else's. In real research, no one else knows the answer to the problems you work on (otherwise why would you be doing them?), so the most important thing you can learn from homework is how to think and solve for yourself, and be confident in your answers.

Steven. Weinberg, "Cosmology" (Oxford U. Pr 2008), ISBN-10 0198526822 The first half has a nice introduction to the observations, history, and fundamentals of cosmology. The second half covers the linear growth of fluctuations (like Dodelson) in a unique way. The book does assume good familiarity with general relativity. The derivations are complete and rigorous. Malcom Longair, "Galaxy formation" (Springer, 2nd edition 2008) ISBN-10: 3540734775. More general than the title: superb coverage of all of cosmology, with emphasis on the observations and physical understanding, rather than mathematical rigour. E.W. Kolb and Michael Turner, "The Early Universe" (A-W 1990), ISBN 0201116030 Getting dated, but the explanations in Chapters 1-5 are superb. Later chapters are good for the early universe<-->particle physics connections not emphasised in this class. P.J.E. Peebles "Principles of Physical Cosmology" (Princeton 1993) ISBN: 0691019339 A classic text, with very complete derivations and coverage -somewhat too complete to make an good text for a course this short, but it is a great reference to have. It is particularly good in its coverage of structure formation, galaxy clustering, cosmological tests, etc. Contains an introduction to general relativity. Its predecessor by the same auther "Physical Cosmology" (Princeton 1971) is much more concise and readable: exceptionally clear, showing its age in the numbers and observations, but not the physics. John Peacock "Cosmological Physics" (Cambridge 1998) ISBN: 0521422701 Also a classic text, with concise summaries of the relevant physics, (GR, gravitational waves, quantum field theory and the standard model) which many find too condensed to be pedagogical, however. It is especially good as an introduction to the interface between particle physics and cosmology, but covers everything else (in less complete fashion than Peebles).
