Probing the kinematics of early-type galaxy halos using planetary nebulae

Coccato, L; Gerhard, Ortwin; Arnaboldi, Magda; Das, P; Douglas, Nigel G; Kuijken, Konrad; Merrifield, M R; Napolitano, N. R.; Noordermeer, E; Romanowsky, A J; Capaccioli, M; Freeman, Kenneth


We present first results of a study of the halo kinematics for a sample of early type galaxies using planetary nebulae (PNe) as kinematical tracers. PNe allow to extend up to several effective radii (Re) the information from absorption line kinematics (confined to within 1 or 2Re), providing valuable information and constraints for merger simulations and galaxy formation models. We find that the specific angular momentum per unit mass has a more complex radial dependence when the halo region is...[Show more]
