supercluster

 

  • A supercluster is a large group of smaller galaxy clusters or galaxy groups;[1] they are among the largest known structures in the universe.

  • The size of the complex of clusters may indicate a wall of galaxies exists there, instead of a single supercluster.

  • Those groups and clusters and additional isolated galaxies in turn form even larger structures called superclusters.

  • The Milky Way is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn is part of the Virgo Supercluster, which is part of the Laniakea
    Supercluster.

  • [17] ; SCL @ 1338+27 at z=1.1: A rich supercluster with several galaxy clusters was discovered around an unusual concentration of 23 QSOs at z=1.1 in 2001.

  • [5] Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years
    to 10 billion light-years, covering more than 5% of the observable universe.

  • [7] List of superclusters Laniakea Supercluster: z = 0.000, Length = 153 Mpc (500 million light-years); Virgo Supercluster: z= 0.000, Length = 33 Mpc (110 million light-years),
    It contains the Local Group with our galaxy, the Milky Way.

  • [16] Additionally, seven smaller groups of galaxies are associated with the supercluster.

  • It consisted of two known rich clusters and one newly discovered cluster as a result of the study that discovered it.

  • [3] Existence The existence of superclusters indicates that the galaxies in the Universe are not uniformly distributed; most of them are drawn together in groups and clusters,
    with groups containing up to some dozens of galaxies and clusters up to several thousand galaxies.

  • At the time of the discovery, it was the largest and most distant supercluster beyond z=0.5 [18][19] ; SCL @ 1604+43 at z=0.9: This supercluster at the time of its discovery
    was the largest supercluster found so deep into space, in 2000.

  • Although superclusters are supposed to be the largest structures in the universe according to the Cosmological principle, larger structures have been observed in surveys,
    including the Sloan Great Wall.
