The Galaxy Environment of Quasars in the Clowes-Campusano Large Quasar Group at z~1.3
C. P. Haines, R. G. Clowes, L. E. Campusano
The Clowes-Campusano Large Quasar Group (LQG) is the largest known structure at high redshifts, with at least 18 quasars at z~1.3 forming a structure ~200 Mpc across. We are conduc…
The Galaxy Environment of Quasars in the z~1.3 Clowes-Campusano Large Quasar Group
C. P. Haines, R. G. Clowes, L. E. Campusano
We report significant associated clustering in the field of a z=1.226 quasar from the Clowes-Campusano LQG in the form of both a factor ~11 overdensity of I-K>3.75 galaxies and red…
