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)

Please note, refreshments including tea, coffee, and snacks are provided on Wednesdays thanks to the dept. and Karen Lynn. Students are expected to help with clean up. Please unplug all kettles and move leftover refreshments either to GL227 (if a colloquium is taking place) or to the kitchen.

Volunteering for Article Summaries
