The 2dF Galaxy Redshift Survey: spectra and redshifts
Matthew Colless,Gavin Dalton,Stephen J. Maddox,William J. Sutherland,Peder Norberg,Shaun Cole,Joss Bland-Hawthorn,Terry J. Bridges,Russell D. Cannon,Chris A. Collins,Warrick J. Couch,Nicholas Cross,K. Deeley,Roberto De Propris,Simon P. Driver,George Efstathiou,Richard S. Ellis,Carlos S. Frenk,Karl Glazebrook,Carole Jackson,Ofer Lahav,Ian Lewis,Stuart Lumsden,Darren Madgwick,John A. Peacock,Bruce A. Peterson,Ian Price,M. Seaborne,Keith Taylor +28 more
TL;DR: The 2dF Galaxy Redshift Survey (2dFGRS) as mentioned in this paper uses the 2DF multifibre spectrograph on the Anglo-Australian Telescope, which is capable of observing 400 objects simultaneously over a 2° diameter field.

TL;DR: In this paper, a power-spectrum analysis of the final 2DF Galaxy Redshift Survey (2dFGRS) employing a direct Fourier method is presented, and the covariance matrix is determined using two different approaches to the construction of mock surveys, which are used to demonstrate that the input cosmological model can be correctly recovered.

TL;DR: In this paper, a power spectrum analysis of the final 2dF Galaxy Redshift Survey is presented, employing a direct Fourier method, and the covariance matrix for the power-spectrum estimates is determined using two different approaches to the construction of mock surveys.

TL;DR: The DEEP2 and COMBO-17 surveys are compared to study luminosity functions of red and blue galaxies to z ~ 1, and the results imply that the number and total stellar mass of blue galaxies have been substantially constant since z = 1, whereas those of red galaxies (near L*) have been significantly rising as mentioned in this paper.
