Galread Extragalactic Discussion Group

When:  Monday every week
Time:   11am-Noon
Format: Remote for Spring 2021

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.
 
During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is projected onto a large screen, and a guest explains the paper, section by section, in greater detail than may be explained within the text of the article. To aid with discussion, only the article PDF is presented -- no powerpoint-style slides. Galread discussions are very friendly and interactive.

If you would like to present at Galread, please contact Meng Gu (Meng.gu[at]princeton.edu)  or Jenny Greene (jgreene[at]astro.princeton.edu).
