Title:The case of the Hydra I cluster: kinematics and stellar populations

Abstract:
Halos of elliptical galaxies grow about four times since z=2. However, the 
mechanisms for this growth is still a matter of debate. Here we present the 
case of NGC 3311 cD galaxy, in the core of the Hydra I cluster. Previous works 
have shown the presence of an off-centered envelope high Sersic index (n=10) 
and at least two disrupting galaxies falling through the system. Taking 
advantage of a novel set of observations with FORS2 at VLT, we present detailed 
maps of kinematics and stellar population properties that confirms the current 
state of interactions around the halo of NGC 3311.
