: 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…
Signature of a massive rotating metal-poor star imprinted in the Phoenix stellar stream
Andrew R. Casey, Alexander P. Ji, Terese T. Hansen +13
The Phoenix stellar stream has a low intrinsic dispersion in velocity and metallicity that implies the progenitor was probably a low mass globular cluster. In this work we use Mage…
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…
Kinematics of Antlia 2 and Crater 2 from The Southern Stellar Stream Spectroscopic Survey (S5)
Alexander P. Ji, Sergey E. Koposov, Ting S. Li +15
We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S5).…
The Magellanic Edges Survey -- II. Formation of the LMC's northern arm
L. R. Cullinane, A. D. Mackey, G. S. Da Costa +3
The highly-substructured outskirts of the Magellanic Clouds provide ideal locations for studying the complex interaction history between both Clouds and the Milky Way (MW). In this…
: The destruction of a bright dwarf galaxy as revealed by the chemistry of the Indus stellar stream
T. T. Hansen, A. P. Ji, G. S. Da Costa +13
The recently discovered Indus stellar stream exhibits a diverse chemical signature compared to what is found for most other streams due to the abundances of two outlier stars, Indu…
