The Cosmology Journal Club is a series of weekly informal
discussions by faculty, postdocs and graduate students of recent
papers published or posted on the arXiv. The scope is meant
to be very broad but the papers should somehow be related to
cosmology. We are hoping theorists, experimentalists and
observers from both the Physics and the Astronomy Departments will
drop by.
Each volunteer should present a paper very briefly (~5 min), and
then the rest can weigh in with comments, questions and complaints
(~5 min). The goal is to keep the entire process very
informal. Our plan is to post on this web page the papers to
be discussed a few days beforehand so participants can read through
them if they want. Last-minute suggestions are welcome.
The Journal Club is held every Monday (unless otherwise noted) from
12:30 - 1:30. Please feel free to bring along your
lunch. It takes place in 5242 Chamberlin Hall. All Faculty,
postdocs, researchers, graduate and undergraduate students with an
interest in Cosmology and Astrophysics are welcome to listen,
suggest and present!
If you have questions or comments about this Journal Club, would
like to propose a topic or volunteer to introduce a paper, please email Hojin Yoo(hyoo6@wisc.edu) .
