Bias in Matter Power Spectra ?
We review the constraints given by the linear matter power spectra data on cosmological and bias parameters, comparing the data from the PSCz survey (Hamilton et al., 2000) and from the matter power spectrum infered by the study of Lyman alpha spectra at z=2.72 (Croft et al., 2000). We consider flat–Λ cosmologies, allowing Λ, H0 and n to vary, and we also let the two ratio factors rpscz and r l...
متن کاملDetecting the Baryons in Matter Power Spectra
We examine power spectra from the Abell/ACO rich cluster survey and the 2dF Galaxy Redshift Survey (2dFGRS) for observational evidence of features produced by the baryons. A non-negligible baryon fraction produces relatively sharp oscillatory features at specific wavenumbers in the matter power spectrum. However, the mere existence of baryons will also produce a global suppression of the power ...
متن کاملWIMP matter power spectra and small scale power generation
Dark Matter (DM) is generally assumed to be massive, cold and collisionless from the structure formation point of view. Although this translates into a scale-free powerlaw matter power spectrum, a more correct statement is that DM indeed experiences collisional damping, but on a scale which is supposed to be too small to be relevant for structure formation. The aim of this paper is to present a...
متن کاملPower Spectra for Cold Dark Matter and its Variants
The bulk of recent cosmological research has focused on the adiabatic cold dark matter model and its simple extensions. Here we present an accurate tting formula that describes the matter transfer functions of all common variants, including mixed dark matter models. The result is a function of wavenumber, time, and six cosmological parameters: the massive neutrino density, number of neutrino sp...
متن کاملImpact of Dark Matter Substructure on the Matter and Weak Lensing Power Spectra
We explore the effect of substructure in dark matter halos on the power spectrum and bispectrum of matter fluctuations and weak lensing shear. By experimenting with substructure in a cosmological N = 5123 simulation, we find that when a larger fraction of the host halo mass is in subhalos, the resulting power spectrum has less power at 1 . k . 100h Mpc−1 and more power at k & 100h Mpc−1. We exp...
