Chemo-dynamics of Accretion Beyond the Local Group
Jacob Arnold (UCSC, UCO)

We present the first kinematic mapping of stellar substructure beyond the Local Group. This significant advance allows examination of extra-galactic accretion histories at a level of detail only previously possible in the closest few galaxies. Additionally, we investigate formational modes for stellar-halo growth by comparing the observed wide-field kinematic and metallicity halo structure of early-type galaxies to state of the art binary merger and cosmological simulations.
