MULTICOLOR PHOTOELECTRIC PHOTOMETRY OF THE NUCLEI OF GALAXIES.
Abstract
Sixty-four galaxies, including forty-four in the region of the Virgo Cluster have been observed photoelectrically in four colors. Five apertures from 10 to 65 arc seconds were used for most of the systems. Four basic types of galaxies are recognized among both spirals and ellipticals: (1) normal systems which become smoothly redder toward the center; (2) relatively blue galaxies with otherwise normal color curves; (3) galaxies with abnormally red nuclei, and (4) galaxies with strong blue nuclei.
