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…
Andromeda XXXVI: discovery of a new ultra-faint dwarf galaxy towards M31
Joanna D. Sakowska, David MartÃnez-Delgado, Michelle L. M. Collins +4
We present deep imaging of Andromeda XXXVI (And XXXVI), a dwarf galaxy discovered through visual inspection of the Pan-Andromeda Archaeological Survey, using observations obtained…
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…
The satellite galaxies of the Milky Way and Andromeda
Amandine Doliva-Dolinsky, Michelle L. M. Collins, Nicolas F. Martin
The satellite galaxies of the Local Group provide us with an important probe of galaxy formation, evolution, and cosmology. The two large spirals that dominate this group -- the Mi…
