The 2dF galaxy redshift survey: near-infrared galaxy luminosity functions
- S. Cole, P. Norberg, K. Taylor
- Physics
- 20 December 2000
We combine the Two Micron All Sky Survey (2MASS) Extended Source Catalogue and the 2dF Galaxy Redshift Survey to produce an infrared selected galaxy catalogue with 17 173 measured redshifts. We use…
The Galaxy in Context: Structural, Kinematic, and Integrated Properties
- J. Bland-Hawthorn, O. Gerhard
- Physics
- 24 February 2016
Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only galaxy whose formation history can be studied using the full distribution of stars from faint dwarfs to…
Galaxy And Mass Assembly (GAMA): stellar mass estimates
- E. Taylor, A. Hopkins, D. Wijesinghe
- Physics
- 2 August 2011
This paper describes the first catalogue of photometrically derived stellar mass estimates for intermediate-redshift (z < 0.65; median z= 0.2) galaxies in the Galaxy And Mass Assembly (GAMA)…
Galaxy ecology: groups and low-density environments in the SDSS and 2dFGRS
We analyse the observed correlation between galaxy environment and Halpha emission-line strength, using volume-limited samples and group catalogues of 24 968 galaxies at 0.05 < z < 0.095, drawn from…
The 2dF Galaxy Redshift Survey: The environmental dependence of galaxy star formation rates near clusters
We have measured the equivalent width of the Hα emission line for 11 006 galaxies brighter than M_b-=-−19 (Ω_Λ = 0.7, Ω_m = 0.3, H_0 = 70 km s^(−1) Mpc^(−1)) at 0.05 < z < 0.1 in the 2dF Galaxy…
The New Galaxy: Signatures of Its Formation
- K. Freeman, J. Bland-Hawthorn
- Physics
- 6 August 2002
▪ Abstract The formation and evolution of galaxies is one of the great outstanding problems of astrophysics. Within the broad context of hierachical structure formation, we have only a crude picture…
The Sydney-AAO Multi-object Integral field spectrograph
- S. Croom, J. Lawrence, M. University
- Physics
- 14 December 2011
We demonstrate a novel technology that combines the power of the multi-object spectrograph with the spatial multiplex advantage of an integral field spectrograph (IFS). The SydneyAAO (Australian…
The 2dF Galaxy Redshift Survey: the power spectrum and the matter content of the Universe
- W. Percival, C. Baugh, K. Taylor
- Physics
- 15 May 2001
The 2dF Galaxy Redshift Survey has now measured in excess of 160 000 galaxy redshifts. This paper presents the power spectrum of the galaxy distribution, calculated using a direct Fourier transform…
The 2dF-SDSS LRG and QSO (2SLAQ) survey: the z < 2.1 quasar luminosity function from 5645 quasars to g=21.85
- G. Richards, S. Croom, D. York
- Physics
- 13 April 2005
We have used the Two-Degree Field (2dF) instrument on the Anglo-Australian Telescope (AAT) to obtain redshifts of a sample of z 21 deep surveys for quasars. The 2SLAQ data exhibit no well-defined…
