Clustering of quasars from the ROE/ESO large-scale AQD survey

The new ROE/ESO large-scale AQD survey for quasars forms a connected area of |~ 200\,deg²| near the South Galactic Pole, and has resulted in the discovery of a total number of quasar candidates that is comparable to the number previously published from all other sources. In this paper we describe a three-dimensional clustering analysis of ~1100 ‘high-probability’ candidates occupying the assigned-redshift band of 1.8–2.4. The analysis is sensitive to very weak clustering – to a level of 7 per cent of our quasars occurring in pairs on scales |~ 5h⁻¹| Mpc – but none is found.
