The Sloan Great Wall (SGW) is a cosmic structure formed by a giant wall of galaxies (a galaxy filament). Its discovery was announced from Princeton University on October 20, 2003, by J. Richard Gott III , Mario Jurić , and their colleagues, based on data from the Sloan Digital Sky Survey .
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 ...
Sloan Great Wall (SDSS Great Wall) 2003 z=0.07804 433 Mpc long This was the largest known galaxy filament to be discovered, [22] until it was eclipsed by the Hercules–Corona Borealis Great Wall found ten years later. Sculptor Wall (Southern Great Wall, Great Southern Wall, Southern Wall) 8000 km/s long 5000 km/s wide
This discovery surpasses the size of the Sloan Great Wall, a galaxy cluster that measured around 1.1 billion light-years in length and was discovered in 2003.
The Hercules–Corona Borealis Great Wall (HCB) [1] [5] or simply the Great Wall [6] is a galaxy filament that is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter).
This graphic represents a large supercluster system, like the BOSS Great Wall, with its clusters, voids, and galaxy filaments. The BOSS Great Wall is a supercluster complex that was identified, using the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey (SDSS), in early 2016.
The Great Wall (also called Coma Wall), sometimes specifically referred to as the CfA2 Great Wall, is an immense galaxy filament. ... Sloan Great Wall; References
The Sloan Great Wall, discovered in 2003, has a length of 423 Mpc, [11] which is marginally larger than the homogeneity scale as defined above. The Huge-LQG is three times longer than, and twice as wide as the Yadav et al. upper limit to the homogeneity scale, and has therefore been claimed to challenge our understanding of the universe on ...
