Evidence for a spatially homogeneous component of the Universe: single galaxies

  • 1. Hale Observatories, California Institute of Technology, Carnegie Institution of Washington

Description

A study of the distribution in the sky of galaxies brighter than 14th magnitude reveals two populations. One strongly clustered population has a covariance function w (theta) approx.theta-1 and contains roughly 60 percent of all galaxies. The remaining galaxies are distributed almost uniformly with w (theta) approx. =0. The two populations are defined by the presence or absence (respectively) of nearby (approximately-less-than45') companions. The implications for the definition of clusters and the field, the growth of structure in the universe, and cosmology are discussed briefly
