We introduce the Uchuu suite of large high-resolution cosmological $N$-body simulations. The largest simulation, named Uchuu, consists of 2.1 trillion ($12800^3$) dark matter particles in a box of 2.0 Gpc/h, and the mass of each particle is $3.27 \times 10^{8}$ Msun/h. The highest resolution simulation, called Shin-Uchuu, consists of 262 billion ($6400^3$) particles in a box of 140 Mpc/h, with a particle mass of $8.97 \times 10^{5}$ Msun/h. Combining these simulations we can follow the… Expand

Simulating cosmic structure formation with the GADGET-4 code
• Physics, Computer Science
• 2020
The GADGET-4 code is able to cope with very large problem sizes, thus allowing accurate predictions for cosmic structure formation in support of future precision tests of cosmology, and at the same time is well adapted to high dynamic range zoom-calculations with extreme variability of the particle number density in the simulated volume.

An excess of small-scale gravitational lenses observed in galaxy clusters
The observed cluster substructures are more efficient lenses than predicted by CDM simulations, by more than an order of magnitude, suggesting that systematic issues with simulations or incorrect assumptions about the properties of dark matter could explain the results. Expand
