The large scale structure of the universe

AIP Conference Proceedings, 1990
Recent developments concerning the large scale structure of the universe are discussed. All seem to indicate inhomogeneities on much larger scales than previously thought. Specific observations from above the atmosphere can aid in understanding several outstanding questions, like the spatial distribution of various absorbers, the global geometry of the

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.

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.

The Large-Scale Structure of the Universe

Physics Bulletin, 1981
P J E Peebles 1980 Princeton: Princeton University Press xiii + 422 pp price £16.50 (£5.60 paperback) This book is concerned with the structure of the universe at scales down to the size of galaxies, and in particular with the problem of why the universe seems to be homogeneous and isotropic on a large scale, and yet matter has aggregated into galaxies

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

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.

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 ...

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

The large scale structure of the universe

1991
We present a catalogue of galaxies from COSMOS scans of 16 second epoch Palomar Observatory Sky Survey (POSS-II) plates. The surveys covers an area of 386 square degrees, and covers 150,000 galaxies in the magnitude range 16.5 ≤ r ≤ 19.0. The plates are divided into a north galactic (7 plates, α ≈ 15[superscript h]0[superscript m],δ ≈ +30°(1950.0), b ≈
