World’s fastest supercomputer simulates black hole jets shaping galaxy clusters

Scientists used Frontier, the world's fastest supercomputer, to simulate how supermassive black holes regulate energy in galaxy clusters through powerful jets shooting material at nearly light speed. The simulation, requiring 700,000 computing hours and over 17,000 GPUs, revealed how these cosmic systems remain stable for billions of years. For the first time, researchers successfully reproduced mysterious gas filaments observed in real galaxy clusters, showing they form through turbulence when cold gases interact with hot intergalactic plasma and magnetic fields. The findings demonstrate that magnetic fields play a crucial role in helping galaxy clusters regulate their energy and maintain cosmic stability.
