Elliptical galaxies are surrounded by extended, diffuse stellar halos. In dense galaxy clusters, these halos interact and may be dissolved to form part of the so-called intracluster light. Through Planetary Nebula stars, it has been possible to investigate the kinematics and dynamics in some of these halos, giving new constraints on the formation and on-going evolution of these galaxies.
