Large Scale Structure of the Universe

2016
The universe is full of stars. But how are all the stars distributed? Are they all huddled together, like freezing people around a fire? Or are they sprinkled evenly, as raisins in bread? The short answer is: both! The longer answer is surprisingly complex.

The Large-Scale Structure of the Universe

Endeavour, 1981
An instant landmark on its publication, this book remains the essential introduction to this vital area of research. Written by one of the world's most esteemed theoretical cosmologists, it provides an invaluable historical introduction to the subject, and an enduring overview of key methods, statistical measures, and techniques for dealing with cosmic

Large-Scale Structure of the Universe

2019
By naked eye, we can easily detect only three galaxies: the Andromeda galaxy in the northern sky, and the Large and Small Magellanic Clouds in the southern sky. Pictures taken via large telescopes contain millions of galaxies, and it is estimated that there are hundreds of billions of faint galaxies all over the sky.

The large-scale structure of the Universe

European Review, 1997
The study of the distribution of matter in the Universe is at the forefront of modern astronomy, and stimulates numerous research programmes both in theory, observation and experiment. The distribution of galaxies has a cell-like structure resulting from the alternation of sheets and voids with the topological properties of a ‘sponge’.

The large-scale structure of the universe

Contemporary Physics, 1996
Abstract The search for a theory that explains the origin of galaxies and large-scale structure in the Universe is at an exciting stage. Observational advances, including measurements of the anisotropy in the cosmic microwave background and systematic surveys of galaxy redshifts, are confronting theoretical calculations of the distribution of matter ...

The large-scale structures of the Universe

Nuclear Physics B - Proceedings Supplements, 2000
Abstract The present status of our understanding of the large-scale structures of the Universes is reviewed. The different methods that have been employed to probe the large-scale structures are presented, together with a discussion of their interests. Special emphasis is put on the implications of the observational results to the dark matter issue.

HIERARCHIES IN THE LARGE-SCALE STRUCTURES OF THE UNIVERSE

International Journal of Modern Physics D, 2006
We study the common relationships that exist between the various structures in the Universe, and show that a unifying description appears when these are considered as emerging from dynamical critical phenomena characterized by complex exponents in the two-point correlation function of matter density fluctuations.

Large Scale Structure of the Universe

2001
Now it is generally recognized that on large scales the universe is isotropic and homogeneous while on smaller scales it is extremely clumpy. Indeed, detected small variations of CMB anisotropy by COBE - ΔT/T ≈ 10−5- restrict the possible inhomogeneities on larger scales, while existence of so prominent galaxy concentrations as, for example, groups and

ON THE UNIVERSAL CHARACTER OF THE LARGE SCALE STRUCTURE OF THE UNIVERSE

International Journal of Modern Physics D, 1992
We review different theories on the formation of the large scale structure of the Universe. Special emphasis is put on the theory of inertial instability. We show that, for a large class of initial spectra, the resulting two point correlation functions are similar.

The Large Scale Structure of the Universe

1989
We discuss the constraints that three different class of observations can set on various model for the formation of the large scale structure of the Universe. These observations involve measurements of galaxy peculiar velocity and gravity, and the cosmic microwave background angular distribution.
