Reconstruction of primordial density fields
The Monge-Ampère-Kantorovich (MAK) reconstruction is tested against cosmological N -body simulations. Using only the present mass distribution sampled with particles, and the assumption of homogeneity of the primordial distribution, MAK recovers for each particle the non-linear displacement field between its present position and its Lagrangian position on a primordial uniform grid. To test the ...
متن کاملReconstruction of cosmological density and velocity fields in the Lagrangian Zel’dovich Approximation
We present a method for reconstructing cosmological density and velocity fields using the Lagrangian Zel’dovich formalism. The method involves finding the least action solution for straight line particle paths in an evolving density field. Our starting point is the final, evolved density , so that we are in effect carrying out the standard Zel’dovich Approximation based process in reverse. Usin...
متن کاملReconstruction of cosmological initial conditions from galaxy redshift catalogues
We present and test a new method for the reconstruction of cosmological initial conditions from a full-sky galaxy catalogue. This method, called ZTRACE, is based on a self-consistent solution of the growing mode of gravitational instabilities according to the Zel’dovich approximation and higher order in Lagrangian perturbation theory. Given the evolved redshift-space density field, smoothed on ...
متن کاملDistributions of Fourier modes of cosmological density fields.
We discuss the probability distributions of Fourier modes of cosmological density fields using the central limit theorem as it applies to weighted integrals of random fields. It is shown that if the cosmological principle holds in a certain sense, i.e., the universe approaches homogeneity and isotropy sufficiently rapidly on very large scales, the one-point distribution of each Fourier mode of ...
متن کاملCharacteristic scales of initial density and velocity fields
For the initial fields of the density contrast and peculiar velocity, we theoretically calculate the ‘differential’ and ‘integral’ length scales, i.e., statistical measures that respectively characterize the small-scale zero crossings and large-scale correlation of a random field. The length scales and associated mass scales are related to the length and mass scales observed for (1) halos of yo...
