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 2dF Galaxy Redshift Survey: The bJ-band galaxy luminosity function and survey selection function
- P. Norberg, S. Cole, K. Taylor
- Physics
- 1 November 2001
We use more than 110 500 galaxies from the 2dF Galaxy Redshift Survey (2dFGRS) to estimate the bJ-band galaxy luminosity function at redshift z = 0, taking account of evolution, the distri- bution of…
The 2dF Galaxy Redshift Survey: power-spectrum analysis of the final data set and cosmological implications
- S. Cole, W. Percival, K. Taylor
- Physics
- 11 January 2005
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing a direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts. We…
The 2dF Galaxy Redshift Survey: correlation functions, peculiar velocities and the matter density of the Universe
- E. Hawkins, S. Maddox, K. Taylor
- Physics
- 17 December 2002
We present a detailed analysis of the two-point correlation function, xi(sigma, pi), from the 2dF Galaxy Redshift Survey (2dFGRS). The large size of the catalogue, which contains similar to220 000…
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…
Dependence of Galaxy Clustering on Luminosity and Spectral Type
- P. Norberg, C. Baugh, the 2dFGRS Team
- Physics
- 3 December 2001
We investigate the dependence of galaxy clustering on luminosity and spectral type using the 2dF Galaxy Redshift Survey (2dFGRS). Spectral types are assigned using the principal-component analysis of…
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 2dF Galaxy Redshift Survey: galaxy luminosity functions per spectral type
- D. Madgwick, O. Lahav, K. Taylor
- Physics
- 11 July 2001
We calculate the optical bJ luminosity function of the 2dF Galaxy Redshift Survey (2dFGRS) for different subsets defined by their spectral properties. These spectrally selected subsets are defined…
Radio sources in the 2dF Galaxy Redshift Survey.
- E. Sadler, C. Jackson, K. Taylor
- Physics
- 10 June 2001
Radio continuum surveys can detect galaxies over a very wide range in redshift, making them powerful tools for studying the distant universe. Until recently, though, identifying the optical…
The 2dF Galaxy Redshift Survey: luminosity dependence of galaxy clustering
- P. Norberg, C. Baugh, the 2dFGRS Team
- Physics
- 29 May 2001
We investigate the dependence of the strength of galaxy clustering on intrinsic luminos- ity using the Anglo-Australian two degree field galaxy redshift survey (2dFGRS). The 2dFGRS is over an order…
