Spherical Harmonic Analysis of the PSCz Galaxy Catalogue: Redshift distortions and the real–space power spectrum
We apply the formalism of spherical harmonic decomposition to the galaxy density field of the IRAS PSCz redshift survey. The PSCz redshift survey has almost all– sky coverage and includes IRAS galaxies to a flux limit of 0.6 Jy. Using maximum likelihood methods to examine (to first order) the distortion of the galaxy pattern due to redshift coordinates, we have measured the parameter β ≡ Ω/b. W...
متن کاملPower Spectrum Analysis of the ESP Galaxy Redshift Survey
We measure the power spectrum of the galaxy distribution in the ESO Slice Project (ESP) galaxy redshift survey. We develope a technique to describe the survey window function analytically, and then deconvolve it from the measured power spectrum using a variant of the Lucy method. We test the whole deconvolution procedure on ESP mock catalogues drawn from large N–body simulations, and find that ...
متن کاملMarkov-chain reconstruction of the 2dF Galaxy Redshift Survey real-space power spectrum
The real-space power spectrum ofL∗ galaxies measured from the 2dF Galaxy Redshift Survey (2dFGRS) is presented. Markov-Chain Monte-Carlo (MCMC) sampling was used to fit radial and angular modes resulting from a Spherical Harmonics decomposition of the 2dFGRS overdensity field (described in Percival et al. 2004) with 16 real-space power spectrum values and linear redshift-space distortion parame...
متن کاملMeasuring the Galaxy Power Spectrum with Future Redshift Surveys
Precision measurements of the galaxy power spectrum P (k) require a data analysis pipeline that is both fast enough to be computationally feasible and accurate enough to take full advantage of high-quality data. We present a rigorous discussion of different methods of power spectrum estimation, with emphasis on the traditional Fourier method, and linear (Karhunen-Loève; KL), and quadratic data ...
متن کاملThe nonlinear redshift-space power spectrum of galaxies
We study the power spectrum of galaxies in redshift space, with third order perturbation theory to include corrections that are absent in linear theory. We assume a local bias for the galaxies: i.e. the galaxy density is sampled from some local function of the underlying mass distribution. We find that the effect of the nonlinear bias in real space is to introduce two new features: first, there...
