Scientific paper

The luminosity functions and the spatial density fields of galaxies of different morphological types are presented and compared. The luminosity function varies as a function of morphology; for irregular and dwarf galaxies it is significantly steeper than for ellipticals and spirals. The density fields of galaxies of different morphological types are compared, and the statistical significance of observed differences are determined with the use of extensive Monte Carlo experiments. Significant differences are found between the density fields of elliptical, spiral, and irregular galaxies, which exist well outside cluster cores. Both ellipticals and spirals tend to be more clustered than irregular galaxies. The ellipticals are more concentrated than the spirals in the Virgo and Ursa Major clusters, but the overdensity of the Local Supercluster outside of the clusters is more pronounced in the spiral sample. The possibility that these effects are partially due to systematic biases with distance in the morphological classifications of galaxies is discussed.
