Colloquia

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.

Do you have a speaker in mind? Submit your suggestions here Speaker Suggestion Form. Sign-up here for the TAP listserv to receive details for each upcoming talk. 

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. Talks are hosted live on Zoom.

    Yu-Dai Tsai, Los Alamos National Laboratory

    Dr. Tsai is a Director’s Fellow at the Los Alamos National Laboratory. He received his PhD at Cornell University and was a postdoc at Fermilab and the University of California, Irvine. Dr. Tsai’s research sits at the intersection of particle physics, astroparticle physics, and cosmology, developing theories, searches, and small-scale experiments to probe fundamental laws of physics. He currently focuses on exploring the Elusive Universe, consisting of dark matter, neutrinos, and gravity, studying their signatures in neutrino experiments, space missions, and quantum sensors. Several of his small-scale experiments and search concepts are being implemented in national laboratories worldwide. One of the ultimate goals of Dr. Tsai is to detect dark matter pure gravitationally in the solar system.

    Yangyang Cai, Shanghai Jiao Tong University and the 2024 TAP Research Prize Winner

    Yangyang is the 2024 TAP Research Prize Awardee for his paper on “Dynamics of Ultra-relativistic Charged Particles with Strong Radiation Reaction. II. Aristotelian Equilibrium State.” Yangyang Cai received is Ph.D. in Physics in 2023; his advisor was Dr. Sam Gralla.

    I’m currently a postdoc at Tsung-Dao Lee Institute of Shanghai Jiao Tong University. I got my bachelor’s degree at Nankai University in China, studying physics. I got my PhD degree at the University of Arizona, studying theoretical astrophysics. During my PhD studies, I mainly focused on extreme electromagnetic fields around black holes such as force-free fields. Recently I have switched from analytic to numeric simulations. I am mainly interested in simulating plasmas around compact objects like black holes and neutron stars using Particle-In-Cell simulations
