For the first time, the “inertial range connecting large and small eddies in accretion disk turbulence” was reproduced.

Black holes cannot be directly detected by ground or space-based telescopes. But the accretion disks of gas, plasma, and dust that orbit them emit detectable electromagnetic radiation, allowing astronomers to infer the presence of black holes.

This process creates intense turbulence, which has been a challenging phenomenon to study. Previous simulations had been limited by computational power, but this new research has broken new ground.

The researchers leveraged the computational power of supercomputers like RIKEN’s “Fugaku” and NAOJ’s “ATERUI II. Interestingly, Fugaku held the title of the world’s fastest computer until 2022.
