David A. Wake, Scott M. Croom, Elaine M. Sadler +1
We examine the clustering properties of low-power radio galaxies at redshift 0.4<z<0.8, using data from the 2SLAQ Luminous Red Galaxy (LRG) survey. We find that radio-detected LRGs…

We report on our further analysis of the expanded and revised sample of potential BL Lac objects (the 2BL) optically identified from two catalogues of blue-selected (UV excess) poi…
The evolution of host mass and black hole mass in QSOs from the 2dF QSO Redshift Survey
S. Fine, S. M. Croom, L. Miller +9
We investigate the relation between the mass of super-massive black holes (Mbh) in QSOs and the mass of the dark matter halos hosting them (Mdh). We measure the widths of broad emi…
Multi-Object Spectroscopy Field Configuration by Simulated Annealing
Brent Miszalski, Keith Shortridge, Will Saunders +2
Multi-object spectroscopy (MOS) instruments, such as the Two-degree Field (2dF) facility of the Anglo-Australian Observatory (AAO), have facilitated large-scale redshift surveys. Y…
MegaZ-LRG: A photometric redshift catalogue of one million SDSS Luminous Red Galaxies

We describe the construction of MegaZ-LRG, a photometric redshift catalogue of over one million luminous red galaxies (LRGs) in the redshift range 0.4 < z < 0.7 with limiting magni…
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…

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…
