Galaxy Simulations in the Era of Exascale - May 19, 2023

Explore a one-hour lecture on cutting-edge galaxy simulation technology and its applications in modern astrophysics research. Learn how computational power has evolved from simulations using millions of cells or particles to today's billions-scale calculations. Discover the groundbreaking potential of GPU-based machines like the exascale-breaking Frontier at Oak Ridge National Lab, and understand the development of the astrophysics code Cholla for executing a revolutionary trillion-cell galaxy simulation. Gain insights into how this ambitious project aims to model star formation, supernovae, and galaxy outflows at an unprecedented scale matching our Milky Way galaxy. Examine how the resulting hundreds of terabytes of data will be analyzed alongside modern galactic surveys to enhance our understanding of galaxy formation, growth, and evolution throughout cosmic history.
