# UCSD Cosmic Microwave Background Radiation Discussion Group

# Summer 2000

We will meet for approximately 1.5 hours each Wednesday, starting
with a brief recap of the previous week, continuing with roughly an hour of
presentation and discussion of the week's topic, and ending with a brief
listing of questions that the next week's presenters should plan to answer.
Speakers should prepare no more than 30-45 minutes of material to allow
time for discussions of concepts and derivations. All participants
are expected to present or co-present a topic.

Suggested reading for each week is listed below (The Astrophysical
Journal is abbreviated as ApJ and Physical Review Letters/D as PRL/D).
If the presenter finds
a particular source or two that (s)he wants people to read before our meeting,
(s)he should email me
and I will list those as "Required" reading. Especially where multiple
textbooks are listed, there may be duplication among these readings, so
choose the author(s) you like best. If you miss a session, the Suggested
readings would be a great way to catch up. A PDF version of Wayne Hu's thesis
with figures that can be downloaded chapter-by-chapter or in its entirety is
located here.

Next meeting: Wednesday, 9/13, 2PM, 329 SERF.
Note below the "Almost Required" assignment for the 8/30 meeting.
