Princeton University Galread [Galactic/Extragalactic Reading Group]

The Hough Stream Spotter: A new Method for Detecting Linear Structure in Resolved Stars and Application to the Stellar Halo of M31

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.
