Large-scale fluctuations in the mass distribution and the microwave background - Nature and evolution
Abstract
Phenomena occurring during the departure from homogeneity by the Universe as structures on scales smaller than galaxy cluster formed are discussed. Constraints on possible analytic descriptions based on data from the 3 K background are outlined, particularly the wavelength dependence required in any study of the microwave background anisotropies. Statistical measurement of galactic distributions, at time relying on redshift measurements, is explored and computer simulations of projections of the spatial distributions are reviewed. The effects of primeval isothermal perturbations are interpreted in terms of the Big Bang model, with attention given to both negligible mass and supermassive neutrinos. Autocorrelation functions are defined for extracting information on the processes which formed galaxies or clusters from temperature fluctuations in the microwave background.
