Where are the stars?
V. R. Eke, C. M. Baugh, S. Cole +3
The 2dFGRS is used in conjunction with the 2MASSXSC to study the near-IR light and stellar mass content of the local Universe. Mock galaxy catalogues, constructed from cosmological…
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…
Disk Galaxy Rotation Curves in Triaxial CDM Halos
E. Hayashi, J. F. Navarro, A. Jenkins +7
We use N-body hydrodynamical simulations to study the structure of disks in triaxial potentials resembling CDM halos. Our analysis focuses on the accuracy of the dark mass distribu…
Theoretical Models of the Halo Occupation Distribution: Separating Central and Satellite Galaxies
Zheng Zheng, Andreas A. Berlind, David H. Weinberg +7
The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at…
The metal enrichment of the intracluster medium in hierarchical galaxy formation models
Masahiro Nagashima, Cedric G. Lacey, Carlton M. Baugh +2
We investigate the metal enrichment of the intracluster medium (ICM) in the framework of hierarchical models of galaxy formation. We calculate the formation and evolution of galaxi…
The 2dF Galaxy Redshift Survey: luminosity functions by density environment and galaxy type
Darren J. Croton, Glennys R. Farrar, Peder Norberg +26
We use the 2dF Galaxy Redshift Survey to measure the dependence of the bJ-band galaxy luminosity function on large-scale environment, defined by density contrast in spheres of radi…
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…
Can the faint sub-mm galaxies be explained in the Lambda-CDM model?
C. M. Baugh, C. G. Lacey, C. S. Frenk +5
We present predictions for the abundance of sub-mm galaxies (SMGs) and Lyman-break galaxies (LBGs) in the CDM cosmology. A key feature of our model is the self-consistent calcul…
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: stochastic relative biasing between galaxy populations
Vivienne Wild, John A. Peacock, Ofer Lahav +26
It is well known that the clustering of galaxies depends on galaxy type.Such relative bias complicates the inference of cosmological parameters from galaxy redshift surveys, and is…
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…
Galaxy groups in the 2dFGRS: the group-finding algorithm and the 2PIGG catalogue
V. R. Eke, C. M. Baugh, S. Cole +25
The construction of a catalogue of galaxy groups from the 2-degree Field Galaxy Redshift Survey (2dFGRS) is described. Groups are identified by means of a friends-of-friends percol…
Galaxy groups in the 2dFGRS: the luminous content of the groups
V. R. Eke, C. S. Frenk, C. M. Baugh +25
The 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue of ~29000 objects is used to study the luminous content of galaxy systems of various sizes. Mock galaxy catalogues co…
The 2dF Galaxy Redshift Survey: The clustering of galaxy groups
Nelson D. Padilla, C. M. Baugh, V. R. Eke +27
We measure the clustering of galaxy groups in the 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue. The 2PIGG sample has 29,000 groups with at least two members. The clus…
The 2dF Galaxy Redshift Survey: higher order galaxy correlation functions
D. J. Croton, E. Gaztanaga, C. M. Baugh +26
We measure moments of the galaxy count probability distribution function in the two-degree field galaxy redshift survey (2dFGRS). The survey is divided into volume limited subsampl…
The 2dF Galaxy Redshift Survey: voids and hierarchical scaling models
D. J. Croton, M. Colless, E. Gaztanaga +26
We measure the redshift space reduced void probability function (VPF) for 2dFGRS volume limited galaxy samples covering the absolute magnitude range M_bJ-5logh=-18 to -22. Theoreti…
The 2dF Galaxy Redshift Survey: Hierarchical galaxy clustering
C. M. Baugh, D. J. Croton, E. Gaztanaga +26
We use the two-degree field Galaxy Redshift Survey (2dFGRS) to test the hierarchical scaling hypothesis: namely, that the -point galaxy correlation functions can be written in t…
