Variations in a Universal Density Profile
  Using a newly-developed modeling technique, we present orbit-based dynamical
models of the Carina, Draco, Fornax, Sculptor, and Sextans dwarf spheroidal
(dSph) galaxies. These models calculate the dark matter profiles
non-parametrically without requiring any assumptions to be made about their
profile shapes. By lifting this restriction we discover a host of dark matter
profiles in the dSphs that are different from the typical profiles suggested by
both theorists and observers. However, when we scale these profiles
appropriately and plot them on a common axis they appear to follow an
approximate r^-1 power law with considerable scatter.
