Aims. Superclusters are the largest relatively isolated systems in the cosmic web. Using the SDSS BOSS survey we search for the largest superclusters in the redshift range 0.43 < z < 0.71. Methods. We generate a luminosity-density field smoothed over 8 h−1Mpc to detect the large-scale over-density regions. Each individual over-density region is defined as single supercluster in the survey. We define the superclusters in the way that they are comparable with the superclusters found in the SDSS…

BOSS Great Wall: morphology, luminosity, and mass

Context. Galaxy superclusters are the largest systems in the Universe that can give us information about the formation and evolution of the cosmic web. Aims. We study the morphology of the

Discovery of a Supercluster Candidate at z ∼ 1.1

We report a promising candidate for a distant supercluster at z ∼ 1.1 in the Dark Energy Survey Science Verification data. We examine smoothed semi-3D galaxy density maps in various photo-z slices.

The whole picture of the large-scale structure of the CL1604 supercluster at z ∼ 0.9

We present the large-scale structure over a more than 50 comoving Mpc scale at $z \sim 0.9$ where the CL1604 supercluster, which is one of the largest structures ever known at high redshifts, is

Sloan Great Wall as a complex of superclusters with collapsing cores

In the cosmic web, galaxy superclusters or their high-density cores are the largest objects that may collapse at present or during the future evolution. We study the dynamical state and possible

Saraswati: An Extremely Massive ∼200 Megaparsec Scale Supercluster

Here we report the discovery of an extremely massive and large supercluster (called Saraswati) found in the Stripe 82 region of SDSS. This supercluster is a major concentration of galaxies and galaxy

The progeny of a cosmic titan: a massive multi-component proto-supercluster in formation at z = 2.45 in VUDS

We unveil the complex shape of a proto-supercluster at z ∼ 2.45 in the COSMOS field exploiting the synergy of both spectroscopic and photometric redshifts. Thanks to the spectroscopic redshifts of

Supercluster A2142 and collapse in action: infalling and merging groups and galaxy transformations

Context. Superclusters with collapsing cores represent dynamically evolving environments for galaxies, galaxy groups, and clusters.Aims. We study the dynamical state and properties of galaxies and


We study the dependence of the number density and properties of quasars on the background galaxy density using the currently largest spectroscopic data sets of quasars and galaxies. We construct a

Traces of Anisotropic Quasi-Regular Structure in the SDSS Data

The aim of this study is to search for quasi-periodical structures at moderate cosmological redshifts z ≲ 0.5. We mainly use the SDSS DR7 data on the luminous red galaxies (LRGs)with redshifts 0.16 ≤

Tracing the cosmic web

The cosmic web is one of the most striking features of the distribution of galaxies and dark matter on the largest scales in the Universe. It is composed of dense regions packed full of galaxies,



The XXL Survey VII. A supercluster of galaxies at z=0.43

Context. The XXL Survey is the largest homogeneous and contiguous survey carried out with XMM-Newton. Covering an area of 50 deg(2) distributed over two fields, it primarily investigates the

SDSS superclusters: morphology and galaxy content

Context. Understanding the formation, evolution and present-day properties of the cosmic web and objects forming it is an important task in cosmology. Aims. We compare the galaxy populations in

Superclusters of galaxies from the 2dF redshift survey - I. The catalogue

We use the 2dF Galaxy Redshift Survey data to compile catalogues of superclusters for the Northern and Southern regions of the 2dFGRS, altogether 543 superclusters at redshifts 0.009 {le} z {le} 0.2.

Cosmology: Meet the Laniakea supercluster

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').

Two New Catalogues of Superclusters of Abell/ACO Galaxy Clusters out to redshift 0.15

We present two new catalogues of superclusters of galaxies out to a redshit of z = 0.15, based on the Abell/ACO cluster redshift compilation maintained by one of us (HA). The first of these

SDSS DR7 superclusters - The catalogues

We have constructed a set of supercluster catalogues for the galaxies from the SDSS survey main and luminous red galaxy (LRG) flux-limited samples. To delineate superclusters, we calculated
