Simeon Bird, an assistant professor of physics and astronomy at UC Riverside, is a member of a team of astrophysicists that has used machine learning to simulate the universe with high resolution in a thousandth of the time conventional methods would take. The researchers uploaded models of a small region of space at both low...

Using a bit of machine learning magic, astrophysicists can now simulate vast, complex universes in a thousandth of the time it takes with conventional methods. The new approach will help usher in a new era in high-resolution cosmological simulations, its creators report in a study published online May 4 in Proceedings of the National Academy...

The Texascale Days event in December 2020 provided an opportunity for nine research groups to use large sections of the National Science Foundation-funded Frontera supercomputer at the Texas Advanced Computing Center (TACC) to solve problems that in many cases have never been attempted. Simeon Bird, professor of physics and astronomy at the University of California...
