SUMMARY

The most detailed large-scale simulation of a galaxy to date was conducted using the Hazel Hen supercomputer in Stuttgart, utilizing 16,000 cores over a year. This simulation encompasses a cube of space measuring over 230 million light-years in diameter and includes more than 20 billion particles, representing dark matter, stars, cosmic gas, magnetic fields, and supermassive black holes (SMBHs). The simulation was intentionally paused before a significant merger event, raising questions about the programming of SMBH evolution versus natural development.

PREREQUISITES
  • Understanding of supercomputing concepts, specifically the Hazel Hen architecture.
  • Familiarity with astrophysical simulations and their parameters.
  • Knowledge of dark matter and its role in cosmic structures.
  • Basic comprehension of supermassive black holes (SMBHs) and their formation theories.
NEXT STEPS
  • Research the architecture and capabilities of the Hazel Hen supercomputer.
  • Explore methods for simulating cosmic structures in astrophysics.
  • Investigate the formation and evolution of supermassive black holes.
  • Learn about the implications of dark matter in large-scale cosmic simulations.
USEFUL FOR

Astronomers, astrophysicists, computational scientists, and anyone interested in the dynamics of galaxy formation and evolution.

"This was made possible by the Hazel Hen supercomputer in Stuttgart, where 16,000 cores worked together for more than a year – the longest and most resource-intensive simulation to date. The simulation itself consists of a cube of space measuring more than 230 million light-years in diameter that contains more than 20 billion particles representing dark matter, stars, cosmic gas, magnetic fields, and supermassive black holes (SMBHs).

Of course they stop the shown simulation right before a major merger looks like it is going to happen lol cool find I wonder whether hey hard programed the SMBH r let them evolve naturally based on the article I presume the prior simulation trade offs and all and too many different ways such SMBH seeds could form.
