Dark Matter in Single and Double Galaxies
Published online by Cambridge University Press: 03 August 2017
Abstract
Analyses of rotation curves of spiral galaxies show that the amount of dark matter in a galaxy can exceed the amount of luminous matter by a factor of 4. Lenticular galaxies also appear to have dark halos, but conflicting results have been obtained for ellipticals. Data for double spiral galaxies confirm the results from rotation curves and suggest that the dark halos do not extend much beyond 5 optical radii R25.
