A Low-Mass Stellar-Debris Stream Associated with a Globular Cluster Pair in the Halo
Zhen Yuan, Jiang Chang, Timothy C. Beers +1
There are expected to be physical relationships between the globular clusters (GCs) and stellar substructures in the Milky Way, not all of which have yet been found. We search for…
Tracing Kinematic and Chemical Properties of Sagittarius Stream by K-Giants, M-Giants, and BHB stars
Chengqun Yang, Xiang-Xiang Xue, Jing Li +12
We characterize the kinematic and chemical properties of 3,000 Sagittarius (Sgr) stream stars, including K-giants, M-giants, and BHBs, select from SEGUE-2, LAMOST, and SDSS s…
Identifying Galactic Halo Substructure in 6D Phase-space Using 13,000 LAMOST K Giants
Chengqun Yang, Xiang-Xiang Xue, Jing Li +6
We construct a large halo K-giant sample by combining the positions, distances, radial velocities, and metallicities of over 13,000 LAMOST DR5 halo K giants with the Gaia DR2 prope…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample. II. 3D asymmetrical kinematics of mono-age populations in the disk between 6 \,kpc
H. -F. Wang, M. López-Corredoira, Y. Huang +11
We perform analysis of the three-dimensional kinematics of Milky Way disk stars in mono-age populations. We focus on stars between Galactocentric distances of and 14 \,kpc, s…
Revealing the Complicated Story of the Cetus Stream with StarGO
Zhen Yuan, M. C. Smith, Xiang-Xiang Xue +5
We use a novel cluster identification tool StarGO to explore the metal poor ([Fe/H] -1.5) outer stellar halo (d 15 kpc) of the Milky Way using data from Gaia, LAMOST and SD…
CALIFA reveals Prolate Rotation in Massive Early-type Galaxies: A Polar Galaxy Merger Origin?
Athanasia Tsatsi, Mariya Lyubenova, Glenn van de Ven +4
We present new evidence for eight early-type galaxies (ETGs) from the CALIFA Survey that show clear rotation around their major photometric axis ("prolate rotation"). These are LSB…
