The research team was led by Keiya Hirashima in Japan. RIKEN, University of Tokyo and Barcelona’s Universitat collaborated closely. They combined astrophysics expertise with high-performance computing and AI.

Seven million CPU cores worked simultaneously to perform the calculations. AI accelerated simulations, reducing run-time dramatically compared to traditional methods.
