The Large Scale Distribution of Galaxies and of Clusters of Galaxies

Abstract

Some features of the large scale distribution of galaxies in the universe were correctly visualized by our predecessors. Others, however, were appraised quite incorrectly or not at all. These latter features are of particular interest to us, because the morphological approach aims before all to establish a representative body of observed facts. We present here the new outlook which is based on more than a decade of work with the powerful Schmidt telescopes on Palomar Mountain. These investigations correct and enlarge the views derived previously from the work with the large reflectors and with medium size wide angle refractors. Some of the changes in our views are as follows (30).
