STELLAR KINEMATICS OF THE ANDROMEDA II DWARF SPHEROIDAL GALAXY

STELLAR KINEMATICS OF THE ANDROMEDA II DWARF SPHEROIDAL GALAXY

We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy Andromeda II (And II) based on Keck DEIMOS spectroscopy of 531 red giant branch stars. Our kinematical sample is among the largest for any M31 satellite and extends out to two effective radii (r_eff = 5.3' …
