It's Not Just Star Formation: A trend of low dark matter densities in the Andromeda dwarf galaxy system
Connor S. Pickett, Michelle L. M. Collins, Justin I. Read +8
Dynamical mass modeling of Andromeda (M31) dwarf spheroidal (dSph) galaxies has revealed a growing trend of lower central dark matter (DM) densities than predicted by pure DM struc…

Mass Modeling the Andromeda Dwarf Galaxies: Andromeda VI and Andromeda XXIII
Connor S. Pickett, Michelle L. M. Collins, R. Michael Rich +7
Accurately mapping the mass profiles of low mass dwarf spheroidal (dSph) galaxies allows us to test predictions made by dark matter (DM) models. To date, such analyses have primari…
