Population Gradients in Local Group Dwarf Spheroidal Galaxies
Population Gradients in Local Group Dwarf Spheroidal Galaxies
We present a systematic and homogeneous analysis of population gradients for the Local Group dwarf spheroidal galaxies (dSph's) Carina, Sculptor, Sextans, Tucana, and Andromeda I–III, V, and VI. For all of the Milky Way companions studied here, we find significant population gradients. The same is true for the remote dSph …
