The Galaxy and Matter Distribution in the NonLinear Regime
Abstract
It is of primary importance to disentangle the presently observed properties of the galaxy distribution that are due to nonlinearity from those that are genuine tracers of the initial conditions. A summary is given here of the results of a series of papers which explored the consequences of a suggestion by Peebles (1980) that the observed powerlaw behavior of the twobody correlation function may be explained by some virialization process. This in turn implies that the Nbody correlation functions are also power laws. Predictions are reviewed which were made for the probability of holes, the galaxy and cluster luminosity functions, and more generally for the probability distribution of galaxy counts in a cell of any size, for the fractal distribution of galaxies and matter, as well as for the cluster distribution in the past, leading to an estimate of the resulting Xray emission and of the fluctuations introduced into the microwave background.
