The 2dF-SDSS LRG and QSO survey: evolution of the clustering of luminous red galaxies since z = 0.6
David A. Wake, Ravi K. Sheth, Robert C. Nichol +17
We present an analysis of the small-to-intermediate scale clustering of samples of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey and the 2dF-SDSS LRG and QSO (2SLA…
The context of the Local Volume: structures and motions in the nearby universe
Matthew Colless
The 6dF Galaxy Survey (6dFGS) and the 2MASS Redshift Survey (2MRS) provide the most complete maps of the large-scale structures and motions in the nearby universe. These maps have…
The 6dF Galaxy Survey: a low-redshift benchmark for bulge-dominated galaxies

We present the reconstructed real-space density and the predicted velocity fields from the Two Mass Redshift Survey (2MRS). The 2MRS is the densest all-sky redshift survey to date…
Central stellar populations of early-type galaxies in low-density environments
M. Collobert, M. Sarzi, R. L. Davies +2
We have investigated the properties of a volume and magnitude limited sample of nearby early type galaxies that were carefully selected from the AAO two degree field galaxy redshif…
The Dipole Anisotropy of the 2mass Redshift Survey
P. Erdogdu, J. P. Huchra, O. Lahav +14
We estimate the flux weighted acceleration on the Local Group (LG) from the near-infrared Two Micron All Sky Redshift Survey (2MRS). The near-infrared flux weighted dipoles are ver…
Eridanus - A Supergroup in the Local Universe?
Sarah Brough, Duncan Forbes, Virginia Kilborn +2
We examine a possible supergroup in the direction of the Eridanus constellation using 6dF Galaxy Survey second data release (6dFGS DR2) positions and velocities together with 2MASS…
Near-Infrared and Optical Luminosity Functions from the 6dF Galaxy Survey
D. Heath Jones, Bruce A. Peterson, Matthew Colless +1
Luminosity functions and their integrated luminosity densities are presented for the 6dF Galaxy Survey (6dFGS). This ongoing survey ultimately aims to measure around 150,000 redshi…
The Near-Infrared Surface Brightness Distribution of NGC4696
P. Arnalte Mur, S. C. Ellis, Matthew Colless
We present H-band observations of the elliptical galaxy NGC4696, the brightest member of the Centaurus cluster of galaxies. We have measured its light profile, using a two-dimensio…
Second Data Release of the 6dF Galaxy Survey
D. Heath Jones, Will Saunders, Mike Read +1
The 6dF Galaxy Survey is measuring around 150000 redshifts and 15000 peculiar velocities from galaxies over the southern sky at |b|>10 degrees. When complete, it will be the larges…
Structural properties of discs and bulges of early-type galaxies
Roelof S. de Jong, Luc Simard, Roger L. Davies +5
We have used the EFAR sample of galaxies to study the light distributions of early-type galaxies. We decompose the 2D light distribution of the galaxies in a flattened spheroidal c…
The Tiling Algorithm for the 6dF Galaxy Survey
Lachlan Campbell, Will Saunders, Matthew Colless
The Six Degree Field Galaxy Survey (6dFGS) is a spectroscopic survey of the southern sky, which aims to provide positions and velocities of galaxies in the nearby Universe. We pres…
