Does the Sagittarius Stream constrain the Milky Way halo to be triaxial?
Rodrigo Ibata, Geraint F. Lewis, Nicolas F. Martin +2
Recent analyses of the stellar stream of the Sagittarius dwarf galaxy have claimed that the kinematics and three-dimensional location of the M-giant stars in this structure constra…
ARGOS II: The Galactic Bulge Survey
K. Freeman, M. Ness, E. Wylie de Boer +8
We describe the motivation, field locations and stellar selection for the ARGOS spectroscopic survey of 28,000 stars in the bulge and inner disk of the Milky Way galaxy across lati…
PAndAS in the mist: The stellar and gaseous mass within the halos of M31 and M33
Geraint F. Lewis, Robert Braun, Alan W. McConnachie +12
Large scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substruc…
Young accreted globular clusters in the outer halo of M31
A. D. Mackey, A. P. Huxor, A. M. N. Ferguson +6
We report on Gemini/GMOS observations of two newly discovered globular clusters in the outskirts of M31. These objects, PAndAS-7 and PAndAS-8, lie at a galactocentric radius of ~87…
Do globular clusters possess Dark Matter halos? A case study in NGC 2419
Rodrigo Ibata, Carlo Nipoti, Antonio Sollima +3
We use recently published measurements of the kinematics, surface brightness and stellar mass-to-light ratio of the globular cluster NGC 2419 to examine the possibility that this G…
Unearthing Foundations of a Cosmic Cathedral: Searching the Stars for M33's Halo
Robert Cockcroft, Alan W. McConnachie, William E. Harris +9
We use data from the Pan-Andromeda Archaeological Survey (PAndAS) to search for evidence of an extended halo component belonging to M33 (the Triangulum Galaxy). We identify a popul…
