This review attempts to place the observations of extragalactic planetary nebulae in the context of galactic dynamics. From this point of view only the radial velocities of the PNe are important. We have built a specialised instrument to detect PNe i

Modern Techniques in Galaxy Kinematics: Results from Planetary Nebula Spectroscopy

Autor: Romanowsky, Aaron J., Douglas, Nigel G., Kuijken, Konrad, Arnaboldi, Magda, Gerssen, Joris, Merrifield, Michael R.

We have observed planetary nebulae (PNe) in several early-type galaxies using new techniques on 4- to 8-meter-class telescopes. We obtain the first large data sets (~ 100 velocities each) of PN kinematics in galaxies at > 15 Mpc, and present some pre

Extragalactic Globular Cluster Systems

We have obtained kinematical data in the halos of the giant ellipticals M49 and M87. These include globular cluster velocities in M49 to 10 R_eff and planetary nebula velocities in M49 and M87 to 4 R_eff. We report initial results, including dynamica
