Euclid Consortium, the worldwide group that manages the European Area Company’s Euclid house telescope, has revealed the biggest ever simulation of the universe. Referred to as Flagship 2, the simulation mapped 3.4 billion galaxies and tracks the gravitational interplay of greater than 4 trillion particles.
Based mostly on an algorithm designed by the astrophysicist Joachim Stadel from the College of Zurich, the simulation was run on Piz Daint, the third strongest supercomputer on the planet. The calculation was carried out again in 2019 and required greater than 80 per cent of the supercomputer’s whole capability.
In a press release, astrophysicist Julian Adamek, who labored on the undertaking, stated that “these simulations are essential for getting ready the evaluation of Euclid’s information.” For these not within the loop, the Euclid house telescope has been discovering and mapping billions of galaxies throughout the universe and finding out the distribution of darkish power and darkish matter since 2023.
The Flagship 2 mock simulation is predicated on the usual cosmological mannequin and makes use of at present obtainable data in regards to the composition and evolution of the universe. And whereas each Stadel and Adamek say that they count on Euclid’s observations to be according to the present mannequin, researchers are enthusiastic about seeing surprising discoveries.
Stadel says that they’re already seeing indications of cracks in the usual mannequin, to which Adamek added, “It is going to be thrilling to see whether or not the mannequin holds up towards Euclid’s excessive precision information – or whether or not we uncover indicators of recent shortcomings.” The simulation may additionally assist us be taught extra in regards to the nature of darkish power, a continuing that explains the growth of the universe. “We are able to see how the Universe expanded at the moment and measure whether or not this fixed actually remained fixed”, says Adamek.
To offer you a fast recap, Euclid is essentially the most detailed map of the cosmos ever made, not solely in scale but additionally in precision. Spectroscopic measurements from the mannequin. Euclid’s information permits scientists to look again as much as 10 billion years within the universe’s historical past, however it’s nonetheless unclear if it would assist us discover solutions. Nonetheless, Stadel believes the mannequin will assist us take a step ahead in understanding the “phenomena that can not be defined inside the present theoretical framework” and there are “probabilities of discovering surprising or uncommon objects.”
