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… Expand

The whole picture of the large-scale structure of the CL1604 supercluster at z ∼ 0.9
We present the large-scale structure over 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, isExpand
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 possibleExpand
Discovery of a Supercluster Candidate at z ∼ 1.1
We report a promising candidate for a distant supercluster at z $\sim 1.1$ in the Dark Energy Survey Science Verification data. We examine smoothed semi-3D galaxy density maps in various photo-zExpand

Quasars as a tracer of large-scale structures in the distant universe
We study the dependence of the number density and properties of quasars on the background galaxy density using the currently largest spectroscopic datasets of quasars and galaxies. We construct aExpand
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,Expand
The Excess Density of Field Galaxies near z ~ 0.56 around the Gamma-Ray Burst GRB021004 Position
We test for reliability any signatures of field galaxies clustering in the GRB021004 line of sight. The first signature is the GRB021004 field photometric redshifts distribution based on the 6-mExpand
