The 2dF Galaxy Redshift Survey: the local E+A galaxy population
Chris Blake, Michael Pracy, Warrick Couch +27
We select a sample of low-redshift (z ~ 0.1) E+A galaxies from the 2dF Galaxy Redshift Survey (2dFGRS). The spectra of these objects are defined by strong hydrogen Balmer absorptio…
The 2dF Galaxy Redshift Survey: Spherical Harmonics analysis of fluctuations in the final catalogue
Will J. Percival, Daniel Burkey, Alan Heavens +26
We present the result of a decomposition of the 2dFGRS galaxy overdensity field into an orthonormal basis of spherical harmonics and spherical Bessel functions. Galaxies are expect…
XMM Cluster Survey: X-ray source identification using the Sloan Digital Sky Survey
Kate R. Land, Robert C. Nichol, Michael Davidson +8
[ABRIDGED] The XMM Cluster Survey (XCS) is predicted to detect thousands of clusters observed serendipitously in XMM-Newton pointings. We investigate automating optical follow-up o…
Substructure Analysis of Selected Low Richness 2dFGRS Clusters of Galaxies
William S. Burgett, Michael M. Vick, David S. Davis +30
Complementary one-, two-, and three-dimensional tests for detecting the presence of substructure in clusters of galaxies are applied to recently obtained data from the 2dF Galaxy R…
The nature of the relative bias between galaxies of different spectral type in 2dFGRS
E. Conway, S. Maddox, V. Wild +29
We present an analysis of the relative bias between early- and late-type galaxies in the Two-degree Field Galaxy Redshift Survey (2dFGRS). Our analysis examines the joint counts in…
The 2dF Galaxy Redshift Survey: The blue galaxy fraction and implications for the Butcher-Oemler effect
Roberto De Propris, Matthew Colless, John Peacock +28
We derive the fraction of blue galaxies in a sample of clusters at z < 0.11 and the general field at the same redshift. The value of the blue fraction is observed to depend on the…
