| The Fundamental Manifold is an extension of the Fundamental Plane formalism for elliptical galaxies. The advance in the Manifold is
that by including a non-linear relationship between M/L (for material inside
of the effective radius) and velocity dispersion, we are now able to
place all systems ranging from the intercluster stellar population of
rich galaxy clusters to dwarf spheroidals all on the same relationship (see
Figure),
with a scatter comparable to what was found for elliptical galaxies alone
in the Fundamental Plane. The implication is that all of these systems
belong to one dynamical family that is driven by the physics of how baryons
pack relative to dark matter as a function of scale. See papers 73 and 76
in publication list for more details.
