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 ...
The Bolshoi Simulation isn't the first large-scale simulation of the universe, but it is the first to rival the extraordinary precision of modern astrophysical observations. [1] The previous largest and most successful simulation of galactic evolution was the Millennium Simulation Project, led by Volker Springel. [11]
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.

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.
An early direct evidence for this cosmic web of gas was the 2019 detection, by astronomers from the RIKEN Cluster for Pioneering Research in Japan and Durham University in the U.K., of light from the brightest part of this web, surrounding and illuminated by a cluster of forming galaxies, acting as cosmic flashlights for intercluster medium ...
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:
A notable active project is the international Virgo Consortium, which focuses on cosmology. In August 2015 during the general assembly of the International Astronomical Union a new commission C.B1 on Computational Astrophysics was inaugurated, therewith recognizing the importance of astronomical discovery by computing.
