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…

Pisces VII/Triangulum III -- M33's second dwarf satellite galaxy

Michelle L. M. Collins, Noushin Karim, David Martinez-Delgado +6

Pisces VII/Triangulum III (Pisc~VII) was discovered in the DESI Legacy Imaging Survey and was shown to be a Local Group dwarf galaxy with follow-up imaging from the 4-m Telescopio…

Andromeda XXV -- a dwarf galaxy with a low central dark matter density

Emily J. E. Charles, Michelle L. M. Collins, R. Michael Rich +7

Andromeda (And) XXV has previously been reported as a dwarf spheroidal galaxy (dSph) with little-to-no dark matter. However, the uncertainties on this result were significant. In t…

Pegasus V -- a newly discovered ultra-faint dwarf galaxy on the outskirts of Andromeda

Michelle L. M. Collins, Emily J. E. Charles, David Martínez-Delgado +5

We report the discovery of an ultra-faint dwarf in the constellation of Pegasus. Pegasus~V (Peg~V) was initially identified in the public imaging data release of the DESI Legacy Im…
