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.
Where to Find Articles
- astro-ph on arXiv: “the firehose,” raw and unfettered
- The Astrophysical Journal: the main U.S. journal for astrophysics
- The Astrophysical Journal: Letters: short articles selected to highlight topics of broad interest
- The Astronomical Journal: complement of ApJ with slightly more observation-oriented content
- Astronomy and Astrophysics: main European journal, letters section at the beginning of each issue, each issue sectioned by topic (not all topics appear in each issue)
- Monthly Notices of the Royal Astronomical Society: main British journal, also has a letters section.
- Astroparticle Physics: some IceCube results are published here, also a good place for dark matter and cosmic ray work
- Physical Review D: broader scope — this is the Physical Review section that includes particle astrophysics and cosmology
