Description
Recent observations have revealed the structural properties of the dark
and luminous mass distribution in galaxies from dwarfs to giants. Their study led to the
vision of a new and amazing scenario. The investigation of single and
coadded objects has in fact shown that the rotation curves of spirals
follow, from their centers out to their virial radii, an universal profile
that implies a tuned combination of their stellar disk and dark halo mass
distributions. The mass distribution of ellipticals and dwarf spheroidals
is found similar. This, alongside with accurate mass modeling of
individual galaxies, poses important challenges to the presently
theoretically favored LCDM Cosmology and indicate a surprising direct interaction between
the dark and the luminous components.
