Inhomogeneous Cosmological Models I
Author: Dominic G. B. Edelen
Publisher:
ISBN:
Category :
Languages : en
Pages : 23
Book Description
Inhomogeneous cosmological models are obtained by a conformal transformation of the line element of the previous homogeneous models. While a detailed correspondence between the predicted properties of the models and observations remains to be demonstrated, the models exhibit a number of features not phenomenologically different from recent observational findings. Mass distributions can be found that reflect actual galactic clustering. For such clusters, the cluster centers have the same predicted distance-velocity relations as found in the homogeneous models and the same red shift relations to within terms of second order. In all cases, dispersion velocities relative to the cluster centers are exhibited. If the cluster centers are assumed to be equally spaced in space, their observed pattern will exhibit a uniform foreshortening for the more distant ones while the nearer objects will show nonuniform foreshortning. Deviations from a regular pattern thus show up in the near field and become asymptotically regular at large distances. (Author).

A BOOK COSMOLOGICAL MODELS

ISBN: 1387106538
Category : Education
Languages : en
Pages : 67
Book Description
A solution of the Einstein equations is by definition cosmological if it can reproduce the Friedmann (1922, 1924), Lemaitre (1927, 1931), Robertson (1929, 1933), and Walker (1935) (FLRW) metric by taking limiting values of arbitrary constants or functions. It has been a conventional wisdom in cosmology that the FLRW models successfully describe the large scale properties of our observed Universe, even since the 1930ies.

Primordial Cosmology
Author: Giovanni Montani
Publisher: World Scientific
ISBN: 9814468339
Category : Science
Languages : en
Pages : 617
Book Description
Primordial Cosmology deals with one of the most puzzling and fascinating topics debated in modern physics — the nature of the Big Bang singularity. The authors provide a self-consistent and complete treatment of the very early Universe dynamics, passing through a concise discussion of the Standard Cosmological Model, a precise characterization of the role played by the theory of inflation, up to a detailed analysis of the anisotropic and inhomogeneous cosmological models. The most peculiar feature of this book is its uniqueness in treating advanced topics of quantum cosmology with a well-traced link to more canonical and pedagogical notions of fundamental cosmology.This book traces clearly the backward temporal evolution of the Universe, starting with the Robertson-Walker geometry and ending with the recent results of loop quantum cosmology in view of the Big Bounce. The reader is accompanied in this journey by an initial technical presentation which, thanks to the fundamental tools given earlier in the book, never seems heavy or obscure.

The Conformal Structure of Space-Times
Author: Jörg Frauendiener
Publisher: Springer
ISBN: 3540458182
Category : Science
Languages : en
Pages : 382
Book Description
Causal relations, and with them the underlying null cone or conformal structure, form a basic ingredient in all general analytical studies of asymptotically flat space-time. The present book reviews these aspects from the analytical, geometrical and numerical points of view. Care has been taken to present the material in a way that will also be accessible to postgraduate students and nonspecialist reseachers from related fields.
