Eigenmode Analysis of Galaxy Distributions in Redshift Space
Eigenmode analysis is one of the most promising methods of analyzing large data sets in ongoing and near-future galaxy surveys. In such analyses, a fast evaluation of the correlation matrix in arbitrary cosmological models is crucial. The observational effects, including peculiar velocity distortions in redshift space, light-cone effects, selection effects, and effects of the complex shape of t...
متن کاملEigenmode Analysis of Galaxy Redshift Surveys I. Theory and Methods
We describe a method for estimating the power spectrum of density fluctuations from galaxy redshift surveys that yields improvement in both accuracy and resolution over direct Fourier analysis. The key feature of this analysis is expansion of the observed density field in the unique set of statistically orthogonal spatial functions which obtains for a given survey’s geometry and selection funct...
متن کاملModelling the redshift-space distortion of galaxy clustering
We use a set of large, high-resolution cosmological N -body simulations to examine the redshift-space distortions of galaxy clustering on scales of order 10− 200hMpc. Galaxy redshift surveys currently in progress will, on completion, allow us to measure the quadrupole distortion in the 2-point correlation function, ξ(σ, π), or its Fourier transform, the power spectrum, P (k, μ), to a high degre...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولThe Durham / UKST Galaxy Redshift Survey - IV . Redshift Space Distortions in the 2 - Point Correlation Function
We have investigated the redshift space distortions in the optically selected Durham/UKST Galaxy Redshift Survey using the 2-point galaxy correlation function perpendicular and parallel to the observer's line of sight, ξ(σ, π). We present results for the real space 2-point correlation function, ξ(r), by inverting the optimally estimated projected correlation function, which is obtained by integ...
