Galaxy clustering morphology and luminosity

The aim of this paper is to study the space distribution of galaxies with a view to determining whether the known morphology–density and luminosity–density relationships are unrelated or are a consequence of different luminosity functions for different morphological types. It is found that morphology and luminosity are two independent parameters that affect both the clustering properties of galaxies and their distribution as a function of the local density, morphology playing the predominant role.
