"Unveiling the Cosmic Tapestry: Computer Simulations Reveal Galaxies' Formation and Large-Scale Structure"

An international team of astrophysicists, including researchers from York University, has developed the MillenniumTNG project, a suite of simulation models that accurately trace the formation of galaxies and cosmic large-scale structure. These simulations, which utilize advanced cosmological codes and supercomputers, provide precise predictions about the distribution of matter and the impact of baryonic processes on galaxy formation. The MillenniumTNG simulations also include the inclusion of massive neutrinos, allowing for meaningful cosmological observations. The first results of the project, published in the Monthly Notices of the Royal Astronomical Society, offer new theoretical predictions and insights into the early universe, intrinsic galaxy alignments, and the clustering of galaxies. These simulations will aid in the analysis of upcoming cosmological data and contribute to a better understanding of the fundamental puzzles of our universe.
