Rotational Kinematics in the Globular Cluster System of M31: Insights from Bayesian Inference
Yuan Li, Brendon J. Brewer, Geraint F. Lewis +1
As ancient stellar systems, globular clusters (GCs) offer valuable insights into the dynamical histories of large galaxies. Previous studies of GC populations in the inner and oute…
Detailed Chemical Abundance Analysis of the Brightest Stars in the Turranburra and Willka Yaku Stellar Streams
Kaitlin B. Webber, Terese T. Hansen, Jennifer L. Marshall +20
We present a detailed chemical abundance analysis of the three brightest known stars from each of the Turranburra and Willka Yaku stellar streams using high-resolution Magellan/MIK…
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…
The Hubble Space Telescope Survey of M31 Satellite Galaxies IV. Survey Overview and Lifetime Star Formation Histories
A. Savino, D. R. Weisz, A. E. Dolphin +35
From orbits of HST imaging, we present deep homogeneous resolved star color-magnitude diagrams that reach the oldest main sequence turnoff and uniformly measured star forma…
