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…
