The 2dF galaxy redshift survey: near-infrared galaxy luminosity functions
- S. Cole, P. Norberg, +24 authors 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: spectra and redshifts
- M. Colless, G.B.Dalton, +26 authors K.Taylor
- Physics
- 27 June 2001
The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observations, the redshift…
Measurements of $\Omega$ and $\Lambda$ from 42 high redshift supernovae
- S. Perlmutter, G. Aldering, +29 authors W. Couch
- Physics
- 1 December 1998
We report measurements of the mass density, Omega_M, and cosmological-constant energy density, Omega_Lambda, of the universe based on the analysis of 42 Type Ia supernovae discovered by the Supernova…
Evolution since Z = 0.5 of the morphology-density relation for clusters of galaxies
- A. Dressler, A. Oemler, +6 authors Bianca M. PoggiantiRay M. Sharples
- Physics
- 21 July 1997
Using traditional morphological classifications of galaxies in 10 intermediate-redshift (z similar to 0.5) clusters observed with WFPC2 on the Hubble Space Telescope, we derive relations between…
The 2dF Galaxy Redshift Survey: The bJ-band galaxy luminosity function and survey selection function
- P. Norberg, S. Cole, +25 authors 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, +28 authors 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 Star Formation Histories of Galaxies in Distant Clusters
- B. Poggianti, I. Smail, +4 authors Richard EllisAugustus Oemler
- Physics
- 20 January 1999
We present a detailed analysis of the spectroscopic catalog of galaxies in 10 distant clusters from Dressler et al. We investigate the nature of the different spectral classes defined by Dressler et…
A Spectroscopic catalog of 10 distant rich clusters of galaxies
- A. Dressler, I. Smail, B. Poggianti, H. Butcher, W. Couch, Richard EllisAugustus Oemler
- Physics
- 20 January 1999
We present spectroscopic observations of galaxies in the fields of 10 distant clusters for which we have previously presented deep imaging with WFPC2 on board the Hubble Space Telescope. The clusters…
A spectroscopic study of three rich galaxy clusters at z = 0.31
- W. Couch, R. Sharples
- Physics
- 1 December 1987
The Homogeneity of Spheroidal Populations in Distant Clusters
- R. Ellis, I. Smail, +4 authors R. Sharples
- Physics
- 29 July 1996
The small scatter observed for the (U-V) colors of spheroidal galaxies in nearby clusters of galaxies provides a powerful constraint on the history of star formation in dense environments. However,…
