Dynamics of Globular Cluster Systems in Elliptical Galaxies
Published online by Cambridge University Press: 03 August 2017
Abstract
One of the most promising avenues for exploring the dynamics of the outer parts of elliptical galaxies involves using bright discrete objects as kinematical tracers: globular clusters and planetary nebulae. As large data sets are becoming available, rigorous dynamical analyses are needed to interpret them. To this end, we have developed an extension of orbit modeling methods, which we apply to the dynamics of the giant ellipticals M87 and M49. We find that a sample of ∼ 200 globular clusters velocities is effective at demonstrating the presence of a dark halo and providing hints about the detailed distribution of the dark matter.
