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]

Structure

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] The supercluster along with the Telescopium−Grus Cloud form parts of a wall bounding the Local Void and the Sculptor Void.[13]

Location of the Pavo-Indus Supercluster relative to other superclusters

Nearby superclusters

Centaurus Supercluster

In 1983, Winkler. et al suggested based on redshift maps of the distribution of galaxies that the Pavo-Indus Supercluster may be connected to the Centaurus Supercluster.[7] Later in 1984, in a collaboration with astronomer Tony Fairall and in a separate paper by Fairall published in 1988 titled A redshift map of the Triangulum Australe-Ara region : further indication that Centaurus and Pavo are one and the same supercluster. it was concluded based on distribution of galaxies in redshift space that the Pavo-Indus supercluster was indeed connected to the Centaurus and Hydra supercluster and that the Virgo Supercluster was an appendage of a larger structure involving these superclusters.[8] Later studies concluded that Pavo-Indus formed part of a wall of galaxies similar in size to the CfA2 Great Wall, dubbed the Norma Wall[17] with the Norma Cluster at its center similar to the Coma Cluster.[18][17] This wall compasses the Pavo-Indus supercluster though the Norma Cluster, passing the ZOA in the Great Attractor region, to meet up with the Centaurus–Crux Cluster at a redshift at about 5,700-6,200 km/s s and the CIZA J1324.7−5736 cluster at a redshift of 5700 km/s[17] while also splitting off to form the Centaurus Wall[19] passing the galactic plane to meet up with Centaurus Cluster[20] where the supercluster originates.[13]

Perseus–Pisces Supercluster

Di Nel la H. et al found no evidence of a connection between Pavo–Indus and the Perseus–Pisces Supercluster.[11] However, Tully et al. revealed the existence of a filamentary extension of the Pavo-Indus Supercluster known as the Arch[10] 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]

Ophiuchus Supercluster

The Pavo–Indus supercluster lies physically close to the Ophiuchus Supercluster and may be connected in an unknown filament between the two superclusters.[21]
