| Abstract: |
Using spectroscopic data taken with Keck II DEIMOS by the Z-PAndAS team in
the Andromeda-Triangulum region, I present a comparison of the disc and
satellite systems of Andromeda with those of our own Galaxy. I discuss the
observed discrepancies between the masses and scale radii of Andromeda dwarf
spheroidal galaxies of a given luminosity with those of the Milky Way. I
also present an analysis of the newly discovered M31 thick disc, which
is measured to be hotter, more extended and thicker than that seen in the
Milky Way. |
