Colloquia 2019-2020


The Department of Physics and Astronomy hosts a colloquium every Wednesday afternoon in 227 Gallalee Hall during the fall and spring semesters (excluding holidays and exam week). Speakers include UA faculty and graduate students as well as researchers from other universities, research institutes, and government agencies. The subject matter ranges from information about the University and department to topics of recent interest in physics and astronomy. Talks are typically 45–50 minutes in length followed by ~10 minutes of questions.

Attendance is free and open to the public. Physics and astronomy graduate students are required to attend colloquia regularly, as determined by their advisors; more information about this requirement may be found in the department’s Graduate Handbook.

Visitor information, including directions and parking details, can be found on our Directions and Parking page.


This semester’s colloquia are listed below. Upcoming colloquia are listed in the left sidebar of this page and under the colloquium category in the department events calendar.

Unless otherwise noted, colloquia are held from 3:45 to 4:45 p.m in 227 Gallalee Hall, with refreshments, including tea, coffee, and cookies, served at 3:30 p.m., in 223 Gallalee Hall.
