Abstract Shortly after its discovery, General Relativity (GR) was applied to predict the behavior of our Universe on largest scales, and later became foundation modern cosmology. Its validity has been verified a range scales environments from Solar system merging black holes. However, experimental confirmations GR cosmological have so far lacked accuracy one would hope for — applications those being largely based extrapolation there sometimes questioned in shadow discovery unexpected cosmic...
ABSTRACT Dark Energy Spectroscopic Instrument (DESI) will construct a large and precise three-dimensional map of our Universe. The survey effective volume reaches $\sim 20\, h^{-3}\, \mathrm{Gpc}^{3}$. It is great challenge to prepare high-resolution simulations with much larger for validating the DESI analysis pipelines. AbacusSummit suite dark-matter-only designed this purpose, $200\, \mathrm{Gpc}^{3}$ (10 times volume) base cosmology. However, further efforts need be done provide more...
