They form the densest part of the large-scale structure of the Universe. In models for the gravitational formation of structure with cold dark matter, the smallest structures collapse first and eventually build the largest structures, clusters of galaxies. Clusters are then formed relatively recently between 10 billion years ago and now.
The largest contiguous feature in the local volume and comparable to the Sloan Great Wall (see above) at half the distance. It is located at the celestial South Pole. King Ghidorah Supercluster (2022) 1,300,000,000 [19] Consists of at least 15 clusters plus other interconnected filaments. It is the most massive galaxy supercluster discovered so ...
Named for its size, El Gordo ("the fat one") is the biggest cluster found in the distant universe (at its distance and beyond), at the time of discovery in 2011, with a mass of 3 quadrillion suns. The second most massive galaxy cluster next to El Gordo is RCS2 J2327 , a galaxy cluster with the mass of 2 quadrillion suns.
A massive galaxy filament, called the Norma Wall (also called Great Attractor Wall [11]) is located at the center of the supposed position of the Great Attractor. The Norma Wall contains the clusters Pavo II, Norma, Centaurus-Crux and CIZA J1324.7−5736. The most massive cluster in this region is the Norma supercluster. [12]
SMACS J0723.3–7327, commonly referred to as SMACS 0723, is a galaxy cluster about 4 billion light years from Earth, [2] within the southern constellation of Volans (RA/Dec = 110.8375, −73.4391667).
Composite image of five galaxies clustered together just 600 million years after the Universe's birth [1]. A galaxy cluster, or a cluster of galaxies, is a structure that consists of anywhere from hundreds to thousands of galaxies that are bound together by gravity, [1] with typical masses ranging from 10 14 to 10 15 solar masses.
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 simultaneous existence of the largest-known voids and galaxy clusters requires about 70% dark energy in the universe today, consistent with the latest data from the cosmic microwave background. [5] Voids act as bubbles in the universe that are sensitive to background cosmological changes.
