The Great Attractor is a region of gravitational attraction in ... The first indications of a deviation from uniform expansion of the universe were reported in 1973 ...
The Laniakea Supercluster (/ ˌ l ɑː n i. ə ˈ k eɪ. ə /; Hawaiian for "open skies" or "immense heaven") [2] or the Local Supercluster (LSC or LS) is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.
It has been found that the Great Attractor and all the galaxies in our region of the universe (including our galaxy, the Milky Way) are moving toward the Shapley Supercluster. [ 5 ] In 2017 it was proposed that the movement towards attractors like the Shapley Attractor in the supercluster creates a relative movement away from underdense areas ...
The dipole repeller is directly opposed to the Shapley Attractor, an over-density of galaxies located in the Shapley Supercluster. The dipole repeller's apparent repulsion is due to matter in the vicinity being pulled towards the Shapley Attractor, along with the Great Attractor. Due to this, the dipole repeller has likely become devoid of ...
The Sloan Great Wall, the Pisces–Cetus Supercluster Complex, the Horologium-Reticulum Supercluster and the Shapley Supercluster as seen in the 2dF Galaxy Redshift Survey This is a list of the largest cosmic structures so far discovered.
[7] [non-primary source needed] This corresponds with the direction of the Great Attractor, which is a gravitational mystery originally discovered in 1973. However, the source of the Great Attractor's attraction was thought to originate from a massive cluster of galaxies called the Norma Cluster, located about 250 million light-years away from ...
Lynden-Bell et al. (1988) dubbed the cause of this the "Great Attractor". The Great Attractor is now understood to be the center of mass of an even larger structure of galaxy clusters, dubbed "Laniakea", which includes the Virgo Supercluster (including the Local Group) as well as the Hydra-Centaurus Supercluster, the Pavo-Indus Supercluster ...
A very large aggregation of galaxies known as the Great Attractor, dominated by the Norma Cluster, is massive enough to affect the local expansion of the Universe. Notable galaxy clusters in the distant, high-redshift universe include SPT-CL J0546-5345 and SPT-CL J2106-5844 , the most massive galaxy clusters found in the early Universe.
