Accreted Globular Clusters and Horizontal Branch Morphology in the Outer Halo of M31

Gracie McGill, Annette M. N. Ferguson, Dougal Mackey +7

M31 hosts a rich population of outer halo ( kpc) globular clusters (GCs), many of which show strong evidence for spatial and/or kinematical associations with la…

Astro2020 Science White Paper: Construction of an L* Galaxy: the Transformative Power of Wide Fields for Revealing the Past, Present and Future of the Great Andromeda System

Karoline M. Gilbert, Erik J. Tollerud, Jay Anderson +34

The Great Andromeda Galaxy (M31) is the nexus of the near-far galaxy evolution connection and a principal data point for near-field cosmology. Due to its proximity (780 kpc), M31 c…
