Boötes III is a Tidally Disrupting Ultra-Faint Dwarf Galaxy on an Eccentric Polar Orbit

Ting S. Li, Denis Erkal, Andrew B. Pace +20

We present updated systemic properties of the ultra-faint dwarf galaxy Boötes III from the Southern Stellar Stream Spectroscopic Survey (S). We identify 21 high-probability mem…

Epicyclic Density Variations in the Indus Stellar Stream

Yong Yang, Geraint F. Lewis, Ting S. Li +12

Longitudinal density fluctuations observed in stellar streams can result from gravitational interactions with massive perturbers in the Milky Way, such as dark matter subhalos. Ana…

: Tidal Disruption in Crater 2 and Formation of Diffuse Dwarf Galaxies in the Local Group

Guilherme Limberg, Alexander P. Ji, Ting S. Li +19

We present results of a spectroscopic campaign around the diffuse dwarf galaxy Crater 2 (Cra2) and its tidal tails as part of the Southern Stellar Stream Spectroscopic Survey ($S^5…

Chemodynamics of BoötesI with : Revised Velocity Gradient, Dark Matter Density, and Galactic Chemical Evolution Constraints

Nathan R. Sandford, Ting S. Li, Sergey E. Koposov +14

We combine new spectroscopic observations of the ultra faint dwarf galaxy (UFD) Boötes I (Boo I) from the Southern Stellar Stream Spectroscopic Survey () with 15 years…

Inactive longitude and superflare in the active single-lined pre-main sequence binary V2279 Cyg

Xueying Hu, Tianqi Cang, Jian-Ning Fu +7

Young, solar-like stars in the pre-main sequence (PMS) stage exhibit vigorous magnetic activity that significantly influences their circumstellar environments and the processes of…

Sifting for a Stream: The Morphology of the Stellar Stream

Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson +18

Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy's gravitational field. Here, we analyze the morphology of the stellar st…

Flipping of the tidal tails of the Ophiuchus stream due to the decelerating Galactic bar

Yong Yang, Geraint F. Lewis, Denis Erkal +16

The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shor…

: New insights from deep spectroscopic observations of the tidal tails of the globular clusters NGC 1261 and NGC 1904

Petra Awad, Ting S. Li, Denis Erkal +22

As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of thes…
