The 2dF Galaxy Redshift Survey: Wiener Reconstruction of the Cosmic Web
Pirin Erdogdu, Ofer Lahav, Saleem Zaroubi +27
We reconstruct the underlying density field of the 2 degree Field Galaxy Redshift Survey (2dFGRS) for the redshift range 0.035<z<0.200 using the Wiener Filtering method. The Wiener…
Galaxy ecology: groups and low-density environments in the SDSS and 2dFGRS
Michael Balogh, Vince Eke, Chris Miller +34
We analyse the observed correlation between galaxy environment and H-alpha emission line strength, using volume-limited samples and group catalogues of 24968 galaxies drawn from th…
The 2dF Galaxy Redshift Survey: Final Data Release
Matthew Colless, Bruce A. Peterson, Carole Jackson +25
The 2dF Galaxy Redshift Survey (2dFGRS) has obtained spectra for 245591 sources, mainly galaxies, brighter than a nominal extinction-corrected magnitude limit of b_J=19.45. Reliabl…
The Properties of Spiral Galaxies: Confronting Hierarchical Galaxy Formation Models with Observations
Eric F. Bell, Carlton M. Baugh, Shaun Cole +2
We compare the properties of local spiral galaxies with the predictions of the Cole et al. semi-analytic model of hierarchical galaxy formation, in order to gain insight into the b…
The 2dF Galaxy Redshift Survey: galaxy clustering per spectral type
D. S. Madgwick, E. Hawkins, O. Lahav +25
We have calculated the two-point correlation functions in redshift space, xi(sigma,pi), for galaxies of different spectral types in the 2dF Galaxy Redshift Survey. Using these corr…
What Shapes the Luminosity Function of Galaxies?
A. J. Benson, R. G. Bower, C. S. Frenk +3
We investigate the physical mechanisms that shape the luminosity function. Beginning with the mass function of dark matter halos, we show how gas cooling, photoionization, feedback…
