M31 Dwarf Galaxy Dark Matter Halos (original) (raw)

2009

Abstract

We marginalize over solutions to the spherical Jeans equation to obtain mass profiles for five Andromeda dwarf spheroidals (dSphs). We analyze stellar kinematics of And I, II, III, X, and XIV, obtained from Keck/DEIMOS spectroscopy, and we compare the mass within 300 parsecs to the Milky Way dSphs.
