NGC 147 and NGC 185, Two New Members of the Local Group of Galaxies
Abstract
NGC 147 and NGC 185-two effiptical nebulae which form a physical pair-have been resolved into stars at the 100-inch reflector on red-sensitive plates. They are new members of the local group of galaxies, of absolute magnitudes -10.3 and -10.6, respectively. In structure they are intermediate between sys- tems like NGC 205, in which the first departures from the highly concentrated form of the typical E-type nebula are noticeable, and the extremely loose Sculptor and Fornax systems. The addition of NGC 147 and NGC 185 increases the number of recognized members of the local group of galaxies to thirteen. A few features of this nearest sample of galaxies are discussed
