Signatures of accretion events in the halos of early-type galaxies from comparing PNe and GCs kinematics

L. Coccato, M. Arnaboldi, O. Gerhard

We have compared the halo kinematics traced by globular clusters (GCs) and planetary nebulae (PNe) for two elliptical galaxies in the Fornax and Virgo clusters NGC 1399 and NGC 464…
