Linear Redshift Distortions
نویسنده
چکیده
Redshift maps of galaxies in the Universe are distorted by the peculiar velocities of galaxies along the line of sight. The amplitude of the distortions on large, linear scales yields a measurement of the linear redshift distortion parameter, which is β ≈ Ω 0.6 0 /b in standard cosmology with cosmological density Ω 0 and light-to-mass bias b. All measurements of β from linear redshift distortions published up to mid 1997 are reviewed.

متن کاملRadial Redshift Space Distortions
The radial component of the peculiar velocities of galaxies cause displacements in their positions in redshift space. We study the effect of the peculiar velocities on the linear redshift space two point correlation function. Our analysis takes into account the radial nature of the redshift space distortions and it highlights the limitations of the plane parallel approximation. We consider the ...
متن کاملRedshift-Space Distortions with the Halo Occupation Distribution I: Numerical Simulations
We show how redshift-space distortions of the galaxy correlation function or power spectrum can constrain the matter density parameter Ωm and the linear matter fluctuation amplitude σ8. We improve on previous treatments by adopting a fully non-linear description of galaxy clustering and bias, which allows us to achieve the accuracy demanded by larger galaxy redshift surveys and to break paramet...
متن کاملRedshift distortions in one-dimensional power spectra
We present a model for one-dimensional (1D) matter power spectra in redshift space as estimated from data provided along individual lines of sight. We derive analytic expressions for these power spectra in the linear and nonlinear regimes, focusing on redshift distortions arising from peculiar velocities. In the linear regime, redshift distortions enhance the 1D power spectra only on small scal...
متن کاملNon-Perturbative Effects of Geometry in Wide-Angle Redshift Distortions
We use the formalism of Szapudi (2004) to extend the theory of large angle redshift distortions. We identify a previously neglected term in the Jacobian, which contains a purely geometric non-linearity while still being linear in terms of the dynamics. We perform linear perturbation theory while keeping these non-perturbative terms intact. The results represent a significant correction to previ...
