Constraints on the Dark Matter from Optical Rotation Curves
Published online by Cambridge University Press: 04 August 2017
Abstract
From the observed rotation curves of Sa, Sb, and Sc spiral galaxies, it is possible to deduce a dozen constraints on the nonluminous matter in spirals. Within the optical image, the dark matter is less concentrated than the luminous, and contributes about 1/2 of the mass, for spirals of all Hubble types and luminosities.
