Astrophysics Seminar/Journal Club

Meeting Time and Format

During Fall and Spring terms, the Astrophysics Seminar/Journal Club meets in 338 Gallalee Hall on

  • Wednesdays from 2:00–3:00 p.m. and
  • Fridays from 2:00–3:00 p.m.

Anyone in the department may attend.

During Summer, we are meeting via Zoom during our normal Friday time.  Please contact one of the organizers for the Zoom meeting information and to be added to the notifications email list.

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 on the Space Telescope Science Institute website.

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 Townsley and Jimmy Irwin.

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.
