The 2dF QSO Redshift Survey - X. Lensing of Background QSOs by Galaxy Groups
A. D. Myers, P. J. Outram, T. Shanks +5
We cross-correlate QSOs from the 2dF Survey with galaxy groups. The galaxy samples are limited to B < 20.5. We use an objective algorithm to detect galaxy groups. A 3sigma anti-cor…
Possible arcminute-separation gravitational lensed QSOs in the 2dF QSO survey
L. Miller, A. M. Lopes, R. J. Smith +4
We report the possible discovery of multiple gravitationally-lensed images of QSOs with angular separations on arcminute scales. The QSOs were selected from the completed 2dF QSO s…
The correlation of line strength with luminosity and redshift from composite QSO spectra
S. M. Croom, K. Rhook, E. A. Corbett +7
We have generated a series of composite QSO spectra using over 22000 individual low resolution (~8A) QSO spectra obtained from the 2dF (18.25<bj<20.85) and 6dF (16<bj<18.25) QSO Re…
The Twice-Overlooked, Second FR II Broad Absorption Line Quasar LBQS 1138-0126
Michael S. Brotherton, Scott M. Croom, Carlos De Breuck +2
We report the correct classification of an overlooked Fanaroff-Riley class II radio-loud quasar with broad absorption lines, only the second such object so identified. The rare pro…
Clustering in the 2dF QSO Redshift Survey
S. M. Croom, B. J. Boyle, N. S. Loaring +5
We present clustering results from the 2dF QSO Redshift Survey (2QZ) which currently contains over 20,000 QSOs at z<3. The two-point correlation function of QSOs averaged over the…
The 2dF QSO Redshift Survey - IX. A measurement of the luminosity dependence of QSO clustering
Scott M. Croom, B. J. Boyle, N. S. Loaring +4
In this Paper we present a clustering analysis of QSOs as a function of luminosity over the redshift range z=0.3-2.9. We use a sample of 10566 QSOs taken from the preliminary data…
