Elliptical Galaxies: Darkly Cloaked or Scantily Clad?
A. J. Romanowsky, N. G. Douglas, K. Kuijken +7
Planetary nebulae (PNe) may be the most promising tracers in the halos of early-type galaxies. We have used multi-object spectrographs on the WHT and the VLT, and the new Planetary…

Is there a dichotomy in the Dark Matter as well as in the Baryonic Matter properties of ellipticals?
N. R. Napolitano, M. Capaccioli, M. Arnaboldi +5
We have found a correlation betwen the M/L global gradients and the structural parameters of the luminous components of a sample of 19 early-type galaxies. Such a correlation suppo…
