  • 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. On the basis of its characteristic size 500 Mpc and longest dimension > 1 Gpc, it is claimed that this structure is incompatible with large-scale homogeneity and the cosmological principle. If true, this would represent a serious challenge to the standard cosmological model. However, the… CONTINUE READING
