Astrophysics Seminar/Journal Club

Meeting Time and Format

During Fall and Spring terms, the Astrophysics Seminar/Journal Club meets in 200 Gallalee Hall on

  • Wednesdays from 2:00–3:00 p.m. and
  • Fridays from 1:00–2:00 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 for Fall 2022 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 Preethi Nair.

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.
