PHEASANT: A Milky Way Built Star by Star
A scientific visualization project presenting exascale simulations of galaxy formation at individual-star resolution.
Field notes
The project presents one continuous numerical universe at several scales: galaxy-wide structure, star-forming regions, and young stellar associations. Its stated performance figures include 5.4 trillion particles, 144 billion particles processed per second, and 0.22-solar-mass mass resolution. The technical stack spans CUDA and SYCL GPU implementations plus x86 and Arm CPU implementations, while an AI surrogate model is described as handling supernova-feedback calculations. Publications, methods, and release notes are listed as forthcoming.
