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: In this paper, a detailed analysis of the two-point correlation function, from the 2dF Galaxy Redshift Survey (2dFGRS), was presented, which can be fit by a power-law, with r_0=5.05+/-0.28 Mpc/h.

TL;DR: In this paper, the authors used the redshifts of more than 141,000 galaxies from the two-degree-field galaxy redshift survey to determine the parameter beta = Omega 0.43 +- 0.07, where Omega is the total mass-density parameter and b is a measure of the bias of the luminous galaxies in the survey.

TL;DR: In this article, the bias parameter of the 2dFGRS data set was used to measure the strength of clustering of the galaxies relative to the mass in the universe, and it was shown that optically selected galaxies do indeed trace the underlying mass distribution.

TL;DR: In this article, the authors investigated the dependence of galaxy clustering on luminosity and spectral type using the 2dF Galaxy Redshift Survey (2dFGRS) using the principal component analysis of Madgwick et al.
