The kinematics of globular clusters and planetary nebula in the core of the Fornax Cluster: intracluster light and the search of stellar streams

I will present recent results of the kinematics of planetary nebulae (PNe) and globular clusters (GCs) out to about 200 kpc from the center of the Fornax cluster. We have collected more than 2000 new radial velocities using VIMOS and FORS2 spectrographs at the VLT which, combined with previous literature, make a unique data sample covering a volume of a galaxy cluster up to about 1/4 of its viral radius.I discuss the signature of an intracluster stellar population both on the velocity field of PNe and GCs and show some preliminary results on the identification of stellar streams in the phase space of the two combined populations.
