A Troublesome Past: Chemodynamics of the Fornax dwarf spheroidal
  We present compelling evidence for the complexity of the Fornax dwarf
spheroidal. By disentangling three different stellar subpopulations in its red
giant branch, we are able to study in detail the dependence between kinematics
and metallicity. A well-defined ordering in velocity dispersion, spatial
concentration, and metallicity is evident in the subpopulations. We also
present evidence for a significant misalignment between the angular momentum
vectors of the old and intermediate-age populations. According to the HST
measurement of Fornax's proper motion, this corresponds to counter-rotation.
These ingredients are used to construct a novel evolutionary history of the
Fornax dwarf spheroidal, characterized as a late merger of a bound pair.
