A survey is given of theories for the origin of large-scale structure in the universe: clusters and superclusters of galaxies, and vast black regions practically devoid of galaxies. Special attention is paid to the theory of a neutrino-dominated universe—a cosmology in which electron neutrinos with a rest mass of a few tens of electron volts would contribute the bulk of the mean density. The evolution of small perturbations is discussed, and estimates are made for the temperature anisotropy of the microwave background radiation on various angular scales. The nonlinear stage in the evolution of smooth irrotational perturbations in a lowpressure medium is described in detail. Numerical experiments simulating large-scale structure formation processes are discussed, as well as their interpretation in the context of catastrophe theory.read more

Formation of galaxies and large-scale structure with cold dark matter
George R. Blumenthal,Sandra M. Faber,Joel R. Primack,Joel R. Primack,Martin J. Rees,Martin J. Rees +5 more
TL;DR: The cold dark matter hypothesis as mentioned in this paper suggests that the dark matter that appears to be gravitationally dominant on all scales larger than galactic cores may consist of axions, stable photinos, or other collisionless particles whose velocity dispersion in the early Universe is so small that fluctuations of galactic size or larger are not damped by free streaming.
Journal ArticleDOI
Giant voids in the Universe
TL;DR: Theories of galaxy formation predict the formation of non-spherical superclusters and giant voids as mentioned in this paper, and large-scale structure changes very slowly, so the currently observed structure reflects the whole history of galaxies formation and structural evolution.

Large scale structure
TL;DR: In this article, a review of catalogues of galaxies, clusters of galaxies and superclusters is given, and the power spectrum of density perturbations and correlation functions are discussed.

Generation of density perturbations in inflationary cosmology
L.A. Kofman,Andrei Linde +1 more
TL;DR: In this article, several different mechanisms of generation of isothermal density perturbations, which can be produced along with the adiabatic (inflaton) perturbation during inflation, are discussed.

Approximation methods for non-linear gravitational clustering
Varun Sahni,Peter Coles +1 more
TL;DR: In this paper, various analytical approximation methods for following the evolution of cosmological density perturbations into the strong (i.e., nonlinear) clustering regime are discussed.

The large-scale structure of the universe
TL;DR: Peebles as discussed by the authors argues that the evolution of the early universe went from a nearly uniform initial state to a progressively more irregular and clumpy universe, based on the largest known structures of the universe.

The large scale structure of the universe I. General properties. One-and two-dimensional models
TL;DR: In this paper, the formation of singularities in the distribution of density in a cold self-gravitating medium in a Friedmann universe was studied, and it was shown that initially smooth perturbations in a self-similar medium can evolve into singularities.
