A successful large-scale simulation of the evolution of galaxies, with results consistent with what is actually seen by astronomers in the night sky, provides evidence that the theoretical underpinnings of the models employed, i.e., the supercomputer implementations ΛCDM, are sound bases for understanding galactic dynamics and the history of the universe, and opens avenues to further research.
This List of Cosmological Computation Software catalogs the tools and programs used by scientists in cosmological research.. In the past few decades, the accelerating technological evolution has profoundly enhanced astronomical instrumentation, enabling more precise observations and expanding the breadth and depth of data collection by several orders of magnitude.
The Millennium Simulation was run in 2005 by the Virgo Consortium, an international group of astrophysicists from Germany, the United Kingdom, Canada, Japan and the United States. It starts at the epoch when the Cosmic microwave background was emitted, about 379,000 years after the universe began.
Galaxy clusters, like RXC J0142.9+4438, are the nodes of the cosmic web that permeates the entire Universe. [53] Video of a cosmological simulation of the local universe, showing large-scale structure of clusters of galaxies and dark matter [54
These are the main structural components of the cosmic web: Voids – vast, largely spherical [6] regions with very low cosmic mean densities, up to 100 megaparsecs (Mpc) in diameter. [7] Walls – the regions that contain the typical cosmic mean density of matter abundance. Walls can be further broken down into two smaller structural features:
Cold streams from the cosmic web feeding a galaxy in the early universe, based on a hydro-cosmological computer simulation (Dekel et al., 2011) The picture shows gas density, extending to a half a million light years, when the Universe was 3 billion years old.
The DTFE has various astrophysical applications, such as the analysis of numerical simulations of cosmic structure formation, the mapping of the large-scale structure of the universe and improving computer simulation programs of cosmic structure formation. It has been developed by Willem Schaap and Rien van de Weijgaert.
In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...
