No quasar clustering at Z > 2.
Abstract
The quasar clustering is analysed using the new Hewitt-Burbidge QSO catalog. The statistical results show some evidence for the evolution of quasar clustering: the quasar clustering exists only for low redshift quasars and no quasar clustering is found at z > 2. These differences are not due to the selection effects on the brightness of quasars with high and low redshifts.
