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…

On the origin of the asymmetric dwarf galaxy distribution around Andromeda

Zhen Wan, William H. Oliver, Geraint F. Lewis +2

The dwarf galaxy distribution surrounding M31 is significantly anisotropic in nature. Of the 30 dwarf galaxies in this distribution, 15 form a disc-like structure and 23 are contai…

The Pristine Inner Galaxy Survey (PIGS) I: Tracing the kinematics of metal-poor stars in the Galactic bulge

Anke Arentsen, Else Starkenburg, Nicolas F. Martin +20

Our Galaxy is known to contain a central boxy/peanut-shaped bulge, yet the importance of a classical, pressure-supported component within the central part of the Milky Way is still…

The Globular Cluster Population of NGC 1052-DF2: Evidence for Rotation

Geraint F. Lewis, Brendon J. Brewer, Zhen Wan

Based upon the kinematics of ten globular clusters, it has recently been claimed that the ultra-diffuse galaxy, NCD 1052-DF2, lacks a significant quantity of dark matter. Dynamical…

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…

Proper Motions of Stellar Streams Discovered in the Dark Energy Survey

N. Shipp, T. S. Li, A. B. Pace +12

We cross-match high-precision astrometric data from Gaia DR2 with accurate multi-band photometry from the Dark Energy Survey (DES) DR1 to confidently measure proper motions for nin…

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…

The Southern Stellar Stream Spectroscopic Survey (): Overview, Target Selection, Data Reduction, Validation, and Early Science

T. S. Li, S. E. Koposov, D. B. Zucker +29

We introduce the Southern Stellar Stream Spectroscopy Survey (), an on-going program to map the kinematics and chemistry of stellar streams in the Southern Hemisphere. The i…
