Perseus–Pegasus Filament

From Wikipedia, the free encyclopedia

The Perseus–Pegasus Filament is a galaxy filament containing the Perseus-Pisces Supercluster and stretching for roughly a billion light years (or over 300/h Mpc). Currently, it is considered to be one of the largest known structures in the universe.[1][note 1] This filament is adjacent to the Pisces–Cetus Supercluster Complex.[2][3]

Discovery[]

The Perseus–Pegasus Filament was discovered by David Batuski and Jack Burns of New Mexico State University in 1985.[3] It is likely that Clyde W. Tombaugh, of the Lowell Observatory, discovered its existence in 1936 while conducting his search for trans-Saturnian planets. He reported it as the Great Perseus-Andromeda stratum of Extra-Galactic Nebulae.[4] Earlier still, parts of this clustering had been reported by  [de].[5]

Notes[]

  1. ^ The reference cited claims the Perseus-Pisces Filament as the largest known structure in the universe. However, various reports cite the Hercules-Corona Borealis Great Wall as the largest at 10,000,000,000 light-years (3.1×109 pc) across.
