Radial motion in the galactic system of globular clusters.
Abstract
It is shown that the radial velocities of globular clusters close to the Galactic Center direction are not consistent with a simple steady-state model of the galactic halo. The result is unlikely to be altered significantly by subsequent improvements in distances, radial velocities, or galactic models. The noncircular motion in this line of sight corresponds to an average of about +60 km/s.
