This Simulation tries to capture that connection between dark matter and the orbital velocity of stars. Adjusting the density of matter in a region of space will affect how fast the stars move around the center of the galaxy.

Introduction: The Millennium Simulation. The Millennium Run used more than 10 billion particles to trace the evolution of the matter distribution in a cubic region of the Universe over 2 billion light-years on a side. It kept busy the principal supercomputer at the Max Planck Society's Supercomputing Centre in Garching, Germany for more than a ...

2023年11月1日 · The new model, named FLAMINGO, is the largest simulation of the universe to take into account the effects of dark matter and ordinary matter.

2024年12月7日 · Last month, a team of researchers put the then-fastest supercomputer in the world to work on a rather large quandary: the nature of the universe’s atomic and dark matter. The supercomputer is...

2024年11月29日 · Researchers used the Frontier supercomputer to conduct the largest astrophysical simulation to date, simulating both atomic and dark matter across universe-sized scales. This was facilitated by advancements in HACC, a code developed to run on exascale-class supercomputers, now capable of performing quintillion calculations per second.

2023年10月23日 · An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets...

This movie shows the dark matter distribution in the universe at the present time, based on the Millennium Simulation, the largest N-body simulation carried out thus far (more than 10 10 particles). By zooming in on a massive cluster of galaxies, the movie highlights the morphology of the structure on different scales, and the large dynamic ...

5 天之前 · These synthetic images allow researchers to study dark matter, dark energy, and galaxy evolution in unprecedented detail. ... an associate professor of physics at Duke University in Durham, North Carolina, who led the simulation campaign. “This is the largest, deepest, most realistic synthetic survey of a mock universe available today ...

The Dark Sky Simulations are an ongoing series of cosmological N-body simulations designed to provide a quantitative and accessible model of the evolution of the large-scale Universe.

2021年12月9日 · We review the field of collisionless numerical simulations for the large-scale structure of the Universe. We start by providing the main set of equations solved by these simulations and their connection with General Relativity.
