Power spectrum from weak-shear data
We demonstrate that the aperture mass as a measure for cosmic shear closely approximates (to better than ≈ 5%) the scaled and shifted power spectrum of the projected mass density. This cosmological weak-lensing information can thus be used to directly infer the projected matter power spectrum with high accuracy. As an application, we show that aperturemass observations can be used to constrain ...
متن کاملThe shear power spectrum from the COMBO-17 survey
We perform a statistical weak lensing or “cosmic shear” analysis of the COMBO-17 survey – a unique dataset with shear quality R-band imaging and accurate photometric redshift estimates (σz = 0.05) for ∼ 90% of galaxies to mR ≤ 24.0. We undertake a full maximum likelihood analysis to measure directly from the data the weak lensing power spectra, C l , C ββ l and C l in 5 band powers from l = 400...
متن کاملA Clustering and Selection Method using Wavelet Power Spectrum
In this paper, we consider the data mining problem of gene selection based on expression data and propose a method based on wavelet power spectrum. Wavelet power spectrum of the data has been analyzed and on the basis of the observations, a parameter was defined and used to select the features. Our proposed method has been applied on three types of cancer datasets. The results are in comparable...
متن کاملA Method for Power Spectrum Parameter Estimation
An asymptotic analysis is carried out for an approximate method of estimating the parameters of the power spectrum of a zero-mean stationary Gaussian random process from an observed realization of limited duration. Maximum likelihood estimates are obtained with the approximation that the coefficients of the Fourier series expansion of the realization are uncorrelated. This is equivalent to othe...
متن کاملConstraining the Power Spectrum using Clusters
We analyze an extended redshift sample of Abell/ACO clusters and compare the results with those coming from numerical simulations of the cluster distribution, based on the truncated Zel’dovich approximation (TZA), for a list of eleven dark matter (DM) models. For each model we run several realizations, so that we generate a set of 48 independent mock Abell/ACO cluster samples per model, on whic...
