The Cosmological History of Accretion onto Supermassive Black Holes
L. Miller, W. J. Percival, S. M. Croom
It is argued that supermassive black holes in the nuclei of galaxies most likely have grown coevally with their host dark matter halos. A calculation based on Press-Schechter withi…
The 2dF QSO Redshift Survey - XV. Correlation analysis of redshift-Space distortions
J. da Angela, P. J. Outram, T. Shanks +6
We analyse the redshift-space (z-space) distortions of QSO clustering in the 2dF QSO Redshift Survey (2QZ). To interpret the z-space correlation function, xi(sigma,pi), we require…
The 2dF-SDSS LRG and QSO Survey: The z<2.1 Quasar Luminosity Function from 5645 Quasars to g=21.85
G. T. Richards, S. M. Croom, S. F. Anderson +25
We have used the 2dF instrument on the AAT to obtain redshifts of a sample of z<3, 18.0<g<21.85 quasars selected from SDSS imaging. These data are part of a larger joint programme:…
On Statistical Lensing and the Anti-Correlation Between 2dF QSOs and Foreground Galaxies
A. D. Myers, P. J. Outram, T. Shanks +5
We cross-correlate APM and SDSS galaxies with background QSOs from the 2dF QSO Redshift Survey, and detect a significant (2.8sigma) anti-correlation. The lack of a signal between 2…
Radio-quiet objects in the 2QZ survey
M. Wals, B. J. Boyle, S. M. Croom +4
Co-addition of blank-field FIRST data at the location of over 8000 QSOs in the 2QZ survey has yielded statistical detections of radio quiet QSOs with median flux levels of 20-40mic…
The first detection of [OIII] emission from high-redshift damped Lyman-alpha galaxies
S. J. Weatherley, S. J. Warren, P. Moller +3
We present the detection of [OIII] emission lines from the galaxies responsible for two high-redshift z>1.75 damped Lyman-alpha (DLA) absorption lines. These are the first detectio…
