A SkyMapper view of the Large Magellanic Cloud: The dynamics of stellar populations
Zhen Wan, Magda Guglielmo, Geraint F. Lewis +2
We present the first SkyMapper stellar population analysis of the Large Magellanic Cloud (hereafter LMC),including the identification of 3578 candidate Carbon Stars through their e…
Two major accretion epochs in M31 from two distinct populations of globular clusters
Dougal Mackey, Geraint F. Lewis, Brendon J. Brewer +12
Large galaxies grow through the accumulation of dwarf galaxies. In principle it is possible to trace this growth history using the properties of a galaxy's stellar halo. Previous i…
Comparing the Quenching Times of Faint M31 and Milky Way Satellite Galaxies
Daniel R. Weisz, Nicolas F. Martin, Andrew E. Dolphin +8
We present the star formation histories (SFHs) of 20 faint M31 satellites () that were measured by modeling sub-horizontal branch (HB) depth color-mag…
A Dwarf Disrupting -- Andromeda XXVII and the North West Stream
Janet Preston, Michelle L. M. Collins, Rodrigo A. Ibata +10
We present a kinematic and spectroscopic analysis of 38 red giant branch stars, in 7 fields, spanning the dwarf spheroidal galaxy Andromeda XXVII and the upper segment of the North…
Detailed study of the Milky Way globular cluster Laevens 3
Nicolas Longeard, Nicolas Martin, Rodrigo A. Ibata +4
We present a photometric and spectroscopic study of the Milky Way satellite Laevens 3. Using MegaCam/CFHT g and i photometry and Keck II/DEIMOS multi-object spectroscopy, we refine…
The Great Escape: Discovery of a nearby 1700 km/s star ejected from the Milky Way by Sgr A*
Sergey E. Koposov, Douglas Boubert, Ting S. Li +17
We present the serendipitous discovery of the fastest Main Sequence hyper-velocity star (HVS) by the Southern Stellar Stream Spectroscopic Survey (S5). The star S5-HVS1 is a $\sim…
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud IV: Evidence for Multiple Populations in Hodge 11 and NGC 2210
Christina K. Gilligan, Brian Chaboyer, Jeffrey D. Cummings +10
We present a multiple population search in two old Large Magellanic Cloud (LMC) Globular Clusters, Hodge 11 and NGC 2210. This work uses data from the Advanced Camera for Surveys a…
The Pristine Dwarf-Galaxy survey - II. In-depth observational study of the faint Milky Way satellite Sagittarius II
Nicolas Longeard, Nicolas Martin, Else Starkenburg +11
We present an extensive study of the Sagittarius II (Sgr II) stellar system using MegaCam g and i photometry, narrow-band, metallicity-sensitive Calcium H&K doublet photometry, aug…
