Developed by an international team of researchersOsho‘, the most realistic virtual simulation of the universe ever achieved, and made possible thanks to ATERUI II, The Japanese supercomputer The most powerful in the world that was built to facilitate the understanding of astronomical phenomena from a theoretical point of view.

This default creation, powered by National Astronomical Observatory of Japan (NAOJ) The Andalusian Institute for Astrophysics (IAA-CSIC) and the Galician Supercomputing Center (CESGA) were involved in the preparation, which will be made available to research groups and From CESGA Cloud Users who want to use it for their studies.

Other research groups from Japan, the United States, Argentina, Australia, Chile, France, and Italy.

“we wait Osho It allows to study the evolution of the universe with a level of detail and an unprecedented volume of information, including the uniqueness of being able to observe the different moments of its time dimension, practically from a distance. the great explosion So far,” notes Francisco Prada, researcher at IAA-CSIC.

This simulation consists of 2,097,152,000,000 (2.1 trillion) particles in a cube that measures 9.630 million light-years on a side, a distance similar to half the distance between Earth and the most distant galaxies observed. CSIC indicates in a note.

For Julia Ferrer, Researcher at IAA-CSIC what do you wear Osho To study the large-scale structure of the universe, “no other simulation is capable of displaying so much information while maintaining such high accuracy. Usually you have to choose between one of the two variables.”

This hypothetical creation can also simulate the evolution of matter during nearly the entire lifetime of the universe: 13.8 billion years of history, thirty times since animal life first left the oceans.

And therefore, Osho It will allow researchers to put forward certain scenarios, such as two black holes colliding in the past, and study these phenomena without resorting to direct observations.

to generate Osho The researchers used all available treatments from ATERUI II supercomputer for a whole year; 40,200 CPU cores running for 48 hours every month to make this project a reality.

How do I explain Tomoaki Ishiyama, of Chiba University (Japan) and responsible for developing and executing the code that would create this simulation, the result was “3 petabytes of data, which is equivalent to approximately one million images.” cell phone 12 mega pixels.

To store such a large amount of information and compress it into a format that can work even in the cloud, the researchers used high-performance computational techniques.

The CESGA, mixed center CSIC And Xunta de Galicia, was responsible for hosting all simulation data.

CATALOGUE Osho Now available in the cloud CESGA And it’s completely free.

“We want Osho Be available to other research groups that may not have the capacity or money to produce their own simulations. Ultimately, this is something that benefits all of us,” says Ferrer.

Products created from this virtual universe will be the key to a better understanding of the mapping of galaxies that will be obtained using ground experiments DESI, PFS and Euclid Space Mission of the European Space Agency (ESA).

Team Osho Also working on a second data release that includes catalogs for Virtual Galaxies and Lens Maps gravity.
