If you have a paper you would like to discuss, please add it to the wiki with a link so that people can download a copy beforehand. While reading the papers prior to the meeting is encouraged, many people find they enjoy coming even without doing so. We have in the past done as many as five papers in one meeting, but at least two per week is our goal. We also encourage exciting, late-breaking submissions from astro-ph. Bragging rights are given for the most interesting paper mentioned at each journal club.
