Large-scale structure in the Universe

  author={Alexander Kashlinsky and Bernard J. T. Jones},
A variety of observations constrain models of the origin of large-scale cosmic structures. Enough observational data have accumulated to constrain (and perhaps determine) the power spectrum of primordial density fluctuations over a very large range of scales, independently of the particular cosmogonical theory assumed. Observations in the near future should be able to weed out many such theories. 

Statistical Analysis of large scale Structure

Observations of the cosmic microwave background isotropy and the global distributions of cosmic objects suggest that the universe is well described by homogeneous Friedman Lemaitre models, at scales

Large-scale structure in the Universe

I present the latest results from three new surveys of the galaxy distribution which have been specially designed to detect large scale structure. The surveys provide strong evidence that our

The structure of the Universe on 100 Mpc Scales

Observational evidence for the presence of a preferred scale around 100 Mpc in the distribution of high-density regions in the Universe is summarised. Toy models with various degrees of regularity

Large scale structure of the Universe: Introduction

The changes of main paradigms on the structure and evolution of the Universe are reviewed. Two puzzles of the modern cosmology, the mean density of matter and the regularity of the Universe on large

Large-scale structure in the universe.

How is the universe organized on large scales? How did this structure evolve from the unknown initial conditions of a rather smooth early universe to the present time? The answers to these questions

Abstract In the Century since Slipher's first observations, roughly three million galaxy redshifts have been measured. The resulting maps of large-scale structure have taught us much of central


Cosmology, high-energy physics and astrophysics are today converging to the study of large scale magnetic fields. While the experimental evidence for the existence of large scale magnetization in

Statistical Analysis of Large-Scale Structure in the Universe

Methods for the statistical characterization of the large-scale structure in the Universe will be the main topic of the present text. The focus is on geometrical methods, mainly Minkowski functionals

Clusters and Large‐Scale Structure

  • Physics
  • 1995
One of the fundamental questions in cosmology is what is the structure of the universe on large scales, and how did it form and evolve. A detailed understanding of this topic should shed light on the



Cosmic microwave background anisotropy

Observation and theory are coming tantalizingly close to measuring the elusive anisotropy, or to revealing that the authors' ideas about the origin of galaxies and large-scale structures are in need of substantial revision.

Large-scale motions in the universe

The present conference on the large-scale motions of the universe discusses topics on the problems of two-dimensional and three-dimensional structures, large-scale velocity fields, the motion of the

Clustering in a neutrino-dominated universe

We have simulated the nonlinear growth of structure in a universe dominated by massive neutrinos using initial conditions derived from detailed linear calculations of earlier evolution. Codes based

Sensitive measurement of fluctuations in the cosmic microwave background

Extensive high sensitivity observations of the cosmic microwave background have been made on an angular scale of 8° covering a substantial fraction of the northern sky. An observed anisotropy in the

Is cosmic drift a cosmic myth

Systematic variations in the mass-to-light ratios of elliptical and spiral galaxies are examined. It is suggested that a major component of the apparent peculiar velocity field on large scales may be

Local gravity and large-scale structure

The magnitude and direction of the observed dipole anisotropy of the galaxy distribution can in principle constrain the amount of large-scale power present in the spectrum of primordial density

The early Universe

In the past few years one of the most exciting areas of research in physics has been the interdisciplinary field of cosmology and particle physics. The NSF's Institute for Theoretical Physics in

Evolution of perturbations in a baryon-dominated universe - Gauge-invariant analysis

The evolution of scalar (density) perturbations in a baryon-dominated universe is comprehensively studied on the basis of a gauge-invariant method. In particular, the residual anisotropies of the

Nonlinear evolution of large-scale structure in the universe

Using N-body simulations we study the nonlinear development of primordial density perturbation in an Einstein--de Sitter universe. We compare the evolution of an initial distribution without

Mapping the Universe

Maps of the galaxy distribution in the nearby universe reveal large coherent structures, including the "Great Wall", one of several serious challenges to current understanding of the origin and evolution of the large-scale distribution of matter in the universe.
