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 12:15 - 1:15. 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 Le Zhang (lzhang263@wisc.edu)
