The aim is to investigate the dynamical properties of high-luminosity spiral galaxies using extended rotation curves.
Sample of 10 high-luminosity spiral galaxies (Sa through Sc)
Accurate rotation curves obtained
Curves extended to about 80% of de Vaucouleurs radii
Accurate rotation profiles developed for the sample galaxies
Revealed systematic trends across different galaxy types
Data support dynamical modeling of spiral galaxies
Abstract
For a sample of 10 high-luminosity spiral galaxies, Sa through Sc, we have obtained accurate rotation curves which extend to about 80% of the de Vaucouleurs radii.
