Meeting Time and Format

The Astrophysics Seminar/Journal Club meets in 338 Gallalee Hall on:
1. Wednesdays from 2:30 – 3:30p.m. and
2. Fridays from 2:00 – 3:00 p.m.
Anyone in the department may attend.

On Wednesday’s we participate in the live broadcast of colloquium talks hosted by NASA/AURA’s Space Telescope Science Institute. The schedule for the talks is available here. The first talk this Fall is on September 6th, 2017.

The Friday meeting consists of two segments:

  • 20-minute talk (+10 minute discussion)
  • article summary and discussion (5-10 minutes)

Volunteering for Article Summaries

Please send your articles to Dean and Jimmy. If your article is too old to be interesting, replace it!

Please propose articles that are fairly recent (within a few months or so), are of interest to you, and you feel you can digest and summarize well. Check out the list of previously presented articles.
