: The Orbital and Chemical Properties of One Dozen Stellar Streams
Ting S. Li, Alexander P. Ji, Andrew B. Pace +19
We report the kinematic, orbital, and chemical properties of 12 stellar streams with no evident progenitors, using line-of-sight velocities and metallicities from the Southern Stel…
Measuring the Mass of the Large Magellanic Cloud with Stellar Streams Observed by
Nora Shipp, Denis Erkal, Alex Drlica-Wagner +16
Stellar streams are excellent probes of the underlying gravitational potential in which they evolve. In this work, we fit dynamical models to five streams in the Southern Galactic…
The dynamics of the globular cluster NGC3201 out to the Jacobi radius
Zhen Wan, William Oliver, Holger Baumgardt +7
As part of a chemo-dynamical survey of five nearby globular clusters with 2dF/AAOmega on the AAT, we have obtained kinematic information for the globular cluster NGC3201. Our new o…
The GALAH+ Survey: Third Data Release
Sven Buder, Sanjib Sharma, Janez Kos +44
The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution of the…
The GALAH Survey: Chemically tagging the Fimbulthul stream to the globular cluster Centauri
Jeffrey D. Simpson, Sarah L. Martell, Gary Da Costa +17
Using kinematics from Gaia and the large elemental abundance space of the second data release of the GALAH survey, we identify two new members of the Fimbulthul stellar stream, and…
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…
The GALAH survey: Co-orbiting stars and chemical tagging
Jeffrey D. Simpson, Sarah L. Martell, Gary Da Costa +24
We present a study using the second data release of the GALAH survey of stellar parameters and elemental abundances of 15 pairs of stars identified by Oh et al 2017. They identifie…
A 10 kpc stellar substructure at the edge of the Large Magellanic Cloud: perturbed outer disk or evidence for tidal stripping?
Dougal Mackey, Sergey E. Koposov, Denis Erkal +3
We report the discovery of a substantial stellar overdensity in the periphery of the Large Magellanic Cloud (LMC), found using public imaging from the first year of the Dark Energy…
