Pavo-Indus Supercluster

The Pavo-Indus Supercluster is a neighboring supercluster located about 60–70 Mpc (196–228 Mly)[3][2][4] away in the constellations of Pavo, Indus, and Telescopium.[5] The supercluster contains three main clusters, Abell 3656, Abell 3698, and Abell 3742.[6]

Other groups and clusters in the supercluster include the NGC 6769 Group and Abell S805 (IC 4765 Group, Pavo II, DRCG 1842-63)[7][8] and the massive Norma Cluster.[9]

In 2014 it was announced that the Pavo-Indus Supercluster is a lobe in a greater supercluster, Laniakea, that is centered on the Great Attractor. The Virgo Supercluster would also be part of this greater supercluster, thus becoming the local supercluster.[10]

StructureEdit

The Pavo-Indus Supercluster exhibits a wall[11][12] or filamentary[13][14][15] structure that extends to a total length of 66 Mpc (215 Mly).[16]

Nearby SuperclustersEdit

Perseus-Pisces SuperclusterEdit

Di Nel la H. et al found no evidence of a connection between Pavo-Indus and the Perseus-Pisces Supercluster.[11] However, Pomarède et al. revealed the existence of a filamentary extension of the Pavo-Indus Supercluster known as the Arch that caps the Local Void in the supergalactic north and provides a connection to the Perseus-Pisces Supercluster[14][15] before terminating close to the NGC 7242 Cluster.[14]
