The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by noon the previous Thursday so a meal can be provided.

Numerical simulations of cosmic structure formation have become a powerful tool in astrophysics. Starting right after the Big Bang, they predict the dark matter backbone of the cosmic web far into the non-linear regime and follow complex galaxy...

Abstract: With only one joint gravitational wave (GW)-electromagnetic (EM) detection to date, observations of the EM counterparts to neutron star mergers are a key path to probing the physics of these unique systems and predicting the behavior of...

Advancements in AI are driving transformative progress in fusion energy. I will provide an overview and highlight the achievements of our group in this area: 1) Robust plasma state prediction even when there is diagnostic failure 2) Finding the...

Differential chromatic refraction (DCR) manifests as a wavelength dependent shift in source position towards the zenith of an observer, and must be corrected for in terrestrial surveys to ensure accurate astrometric solutions. Despite this, DCR can...
