I graded the last problem set (#9) and returned them to
your Physics Department mailboxes, along with your final grade.
I have posted my solutions to the last (9th) problem set.
I have also posted my notes on non-standard BBN and some of
the BBN constraints which I discussed in the last lecture.
The first version of these (BBN) notes lacked 2 of the 5 pages.
This problem has now been resolved. I have posted the revised
notes on inflation which I used for my discussion in our
In the week 9 notes I have posted an updated version of the
powerpoint file(s) in the week 8 notes. I have also posted an
updated (2010) version of the bbnkeys file.
I've revised my notes on calculating the relic abundance of a
massive particle and posted the revised notes (relic_abundance.pdf)
in the week 8 notes. In preparing these notes I (think I) have
identified an error in the week 5 notes on Thermal Distributions
(statmech2.pdf). On p. 6 of those notes the expression for the
ratio of a non-relativistic particle to a photon (by number) has
an incorrect coefficient (check me on this). I believe
the result in eq. 3a on p. 3 of this week's new notes is correct.
The solutions to all 9 problem sets are posted below.
The notes I use for this class are handwritten and consist mainly
of equations and key words (without much, if any, accompanying text).
I post these notes below in the hope that they save you the hassle of
trying to copy everything from the board, while trying to understand
the subject matter at the same time. I would appreciate feedback on
whether these notes are useful.
The weekly problem sets will be assigned on Mondays and collected
at the end of the following Monday's recitation. It is important to
try the problems even if you fail to get them right (the first time).
The problem sets and their solutions will be posted in the table below.
While there is no "official" textbook for the class, here are some
Gravitation and Cosmology, S. Weinberg (Wiley)
Relativistic Astrophysics, Vol. 2, The Structure and Evolution of the
Universe, Ya. B. Zeldovich and I. D. Novikov (U. of Chicago Press)
The Early Universe, E.W. Kolb and M.S. Turner (Addison Wesley)
Cosmological Physics, J. Peacock (Cambridge Univ. Press)
Modern Cosmology, S. Dodelson (London Academic)
Introduction to Cosmology, B. Ryden (Addison Wesley)
The first three texts are older and can be trusted for their
discussions of the physics. The observational data they use
is most likely outdated and should be viewed with great
caution (caveat emptor!).
