  • 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… CONTINUE READING
