Toward a detailed view on the kinematics of intermediate luminosity early-type galaxies no dark matter candidates

Abstract
In several nearby intermediate luminosity early-type galaxies, recent observations at large radii have shown a indications of a lack of dark matter, substantially at odds with the prediction from the CDM hierarchical merger models. Here we discuss a pilot observational project for the study of the internal kinematical and dynamical properties of this remarkable sample of galaxies. Using the VIMOS-IFU in its high spectral resolution mode, it would be possible to investigate the regions up to about 1.2 effective radii, taking advantage of the much larger field of view and telescope diameter. This will allow to disclose the presence of any kinematical substructures which could affect the conclusion on the mass modeling and definitely clarify the inner structure of this particular class of early-type galaxies.
