TAP Colloquia
Each semester the TAP Colloquia Committee invites new speakers working across all fields of theoretical astrophysics to share their current research. Along with providing a one-hour colloquium, each speaker also meets with faculty and students while on campus to discuss research more in depth. The TAP Colloquia series offers 5-6 talks on a bi-weekly basis. The goal of this program activity is to bring scholars to the UA campus to discuss new research, support shared research efforts and cross-fertilization, and increase awareness and communication across the broader U.S. community working in theoretical astrophysics.
Colloquia are held in person in the Gerard P. Kuiper Space Sciences Building, Room 312, Mondays, 3:30 - 4:30 pm.
Please join us for refreshments starting at 3:00 pm in the Kuiper 3rd Floor Atrium.
