Galaxies congregate in clusters and along filaments, and are missing from large regions referred to as voids. These structures are seen in maps derived from spectroscopic surveys that reveal networks of structure that are interconnected with no clear boundaries. Extended regions with a high concentration of galaxies are called ‘superclusters’, although this term is not precise. There is, however, another way to analyse the structure. If the distance to each galaxy from Earth is directly… 

Cosmology: Meet the Laniakea supercluster

TLDR
An analysis of a three-dimensional map of galaxies and their velocities reveals the hitherto unknown edges of the large system of galaxies in which the authors live — dubbed the Laniakea supercluster, named from the Hawaiian lani and akea ('heaven' and 'spacious').

THE ARROWHEAD MINI-SUPERCLUSTER OF GALAXIES

Superclusters of galaxies can be defined kinematically from local evaluations of the velocity shear tensor. The location where the smallest eigenvalue of the shear is positive and maximal defines the

Identification of filamentary structures in the environment of superclusters of galaxies in the Local Universe

Context.Characterization of the internal structure of the superclusters of galaxies (walls, filaments, and knots where the clusters are located) is crucial for understanding the formation of the

Structure and dynamics of the supercluster of galaxies SC0028-0005

According to the standard cosmological scenario, superclusters are objects that have just passed the turn around point and are collapsing. The dynamics of very few superclusters have been analysed up

The Cosmic V-Web

The network of filaments with embedded clusters surrounding voids, which has been seen in maps derived from redshift surveys and reproduced in simulations, has been referred to as the cosmic web. A

The Corona Borealis supercluster: connectivity, collapse, and evolution

Context. Rich superclusters of galaxies represent dynamically active environments in which galaxies and their systems form and evolve. Aims. We study the dynamical properties and connectivity of the

LARGE-SCALE FILAMENTARY STRUCTURES AROUND THE VIRGO CLUSTER REVISITED

We revisit the filamentary structures of galaxies around the Virgo cluster, exploiting a larger data set, based on the HyperLeda database, than previous studies. In particular, this includes a large

Action Dynamics of the Local Supercluster

The fully nonlinear gravitationally induced trajectories of a nearly complete set of galaxies, groups, and clusters in the Local Supercluster are constructed in a numerical action method model

Collapse, Connectivity, and Galaxy Populations in Supercluster Cocoons: the Case of A2142

The largest galaxy systems in the cosmic web are superclusters, overdensity regions of galaxies, groups, clusters, and filaments. Low-density regions around superclusters are called basins of

How did the Virgo cluster form

While the Virgo cluster is the nearest galaxy cluster and therefore the best observed one, little is known about its formation history. In this paper, a set of cosmological simulations that resemble

The distribution of galaxies in the direction of the 'Great Attractor'

THE discovery of galaxy streaming motions of up to 600 km s−1 towards Hydra–Centaurus has led to the suggestion1 that this motion is induced by a concentration of galaxies (the 'Great Attractor')
