The 2dF Galaxy Redshift Survey: The bias of galaxies and the density of the Universe
Licia Verde, Alan F. Heavens, Will J. Percival +27
We compute the bispectrum of the 2dF Galaxy Redshift Survey (2dFGRS) and use it to measure the bias parameter of the galaxies. This parameter quantifies the strength of clustering…
Star Formation, Metallicity and Dust Properties Derived from the SAPM Galaxy Survey Spectra
S. Charlot, G. Kauffmann, M. Longhetti +4
We have derived star formation rates (SFRs), gas-phase oxygen abundances and effective dust absorption optical depths for a sample of galaxies drawn from the Stromlo-APM redshift s…
The 2dF Galaxy Redshift Survey: constraints on cosmic star-formation history from the cosmic spectrum
I. K. Baldry, K. Glazebrook, C. M. Baugh +25
We present the first results on the history of star formation in the Universe based on the `cosmic spectrum', in particular, the volume-averaged, luminosity-weighted, stellar absor…
Optical identifications of radio sources at the 1 mJy level
M. Magliocchetti, S. J. Maddox
We present an analysis of the properties of optical counterparts of radio sources down to 1 mJy. Optical identifications have been obtained by matching together objects from the AP…
The 2dF Galaxy Redshift Survey: Spectra and redshifts
Matthew Colless, G. B. Dalton, S. J. Maddox +26
The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250000 galaxies. This paper describes the survey design, the spectroscopic observations,…
The 2dF Galaxy Redshift Survey: Luminosity dependence of galaxy clustering
P. Norberg, C. M. Baugh, E. Hawkins +23
We investigate the dependence of the strength of galaxy clustering on intrinsic luminosity using the Anglo-Australian two degree field galaxy redshift survey (2dFGRS). The 2dFGRS i…
