A Large Quasar Group (LQG) of particularly large size and high membership has been identified in the DR7QSO catalogue of the Sloan Digital Sky Survey. It has characteristic size (volume 1/3 ) � 500 Mpc (proper size, present epoch), longest dimension � 1240 Mpc, membership of 73 quasars, and mean redshift ¯ = 1.27. In terms of both size and membership it is the most extreme LQG found in the DR7QSO catalogue for the redshift range 1.0 6 z 6 1.8 of our current investigation. Its location on the…

Compatibility of the large quasar groups with the concordance cosmological model

We study the compatibility of large quasar groups with the concordance cosmological model. Large quasar groups are very large spatial associations of quasars in the cosmic web, with sizes of 50–250

The Subaru HSC Galaxy Clustering with Photometric Redshift. I. Dark Halo Masses versus Baryonic Properties of Galaxies at 0.3 ≤ z ≤ 1.4

We present the clustering properties of low-z (z ≤ 1.4) galaxies selected by the Hyper Suprime-Cam Subaru Strategic Program Wide layer over 145 deg2. The wide-field and multiwavelength observation

In light of recent debates on the existence of a gigaparsec-scale structure traced by gamma-ray bursts, namely the Hercules-Corona Borealis Great Wall (HCBGW), we revisit large-scale homogeneity in

Seeing patterns in noise: gigaparsec-scale ‘structures’ that do not violate homogeneity

Clowes et al. (2013) have recently reported the discovery of a Large Quasar Group (LQG), dubbed the Huge-LQG, at redshift z 1:3 in the Data Release 7 quasar catalogue of the Sloan Digital Sky Survey.

Possible structure in the GRB sky distribution at redshift two

Context. Research over the past three decades has revolutionized cosmology while supporting the standard cosmological model. However, the cosmological principle of Universal homogeneity and isotropy

The clustering of gamma-ray bursts in the Hercules–Corona Borealis Great Wall: the largest structure in the Universe?

The Hercules-Corona Borealis Great Wall is a statistically significant clustering of gamma-ray bursts around redshift 2. Motivated by recent theoretical results indicating that a maximal Universal

Environments of strong/ultrastrong, ultraviolet Fe II emitting quasars

We have investigated the strength of ultraviolet (UV) Fe ii emission from quasars within the environments of large quasar groups (LQGs) in comparison with quasars elsewhere, for 1.1 ≤ z_(LQG) ≤ 1.7,

The Galaxy–Halo Connection in High-redshift Universe: Details and Evolution of Stellar-to-halo Mass Ratios of Lyman Break Galaxies on CFHTLS Deep Fields

We present the results of clustering analyses of Lyman break galaxies (LBGs) at , 4, and 5 using the final data release of the Canada–France–Hawaii Telescope Legacy Survey (CFHTLS). Deep- and

Testing the homogeneity of the Universe using gamma-ray bursts

Aims. The discovery of a statistically significant clustering in the distribution of gamma-ray bursts (GRBs) has recently been reported. Given that the cluster has a characteristic size of 2000‐3000

Differential expansion of space and the Hubble flow anisotropy

The Universe on scales $10-100~h^{-1}$ Mpc is dominated by a cosmic web of voids, filaments, sheets and knots of galaxy clusters. These structures participate differently in the global expansion of



Large-Scale Structure at z = 1.2 Outlined by Mg II Absorbers

The largest known structure in the high-redshift universe is mapped by at least 18 quasars and spans ~5° × 2.°5 on the sky, with a quasar spatial overdensity of 6-10 times above the mean. This large

Two close large quasar groups of size ∼ 350 Mpc at

The Clowes & Campusano large quasar group (LQG) at  has been re-examined using the quasar data from the DR7QSO catalogue of the Sloan Digital Sky Survey. In the 1991 discovery, the LQG impinged on

Two 100-Mpc-scale structures in the three-dimensional distribution of radio galaxies and their implications

We present unequivocal evidence for a huge (80 x 100 x 100 Mpc 3 ) superstructure at redshift z = 0.27 in the three-dimensional distribution of radio galaxies from the Texas-Oxford NVSS Structure 08

The space distribution of quasars

The space distribution of quasars from the 2dF and SDSS DR5 catalogs in the redshift interval 0.3 < z < 1.9 is analyzed. The distributions of quasars in both catalogs are found to have the following

Excess clustering on large scales in the MegaZ DR7 photometric redshift survey.

A large excess of power is observed in the statistical clustering of luminous red galaxies in the photometric SDSS galaxy sample called MegaZ DR7, which implies an anomaly on the largest physical scales probed by galaxies.


Large galaxy redshift surveys have long been used to constrain cosmological models and structure formation scenarios. In particular, the largest structures discovered observationally are thought to

ABSTRACT We are looking at quasar environment in the context of large-scale structure (LSS) —a new approach, giving a more informed interpretation of quasar-galaxy correlations.This paper presents
