The complex kinematics of the young stars orbiting the supermassive black hole in the Galactic center can be explained by the presence of an intermediate mass companion of Sgr A
Xiaochen Zheng, Long Wang, Douglas N. C. Lin +2
The sub-parsec proximity around the Sgr A supermassive black hole (SMBH) in the center of the Milky Way contains an inner cluster of eccentric S-stars with randomly oriente…
Potential Impact of the Sagittarius Dwarf Galaxy on the Formation of Young O-rich Stars
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +11
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notab…
Characterising abundance-age relations of GALAH stars using oxygen-enhanced stellar models
Tiancheng Sun, Xunzhou Chen, Shaolan Bi +3
Main Sequence Turn-off stars (MSTO) and subgiant stars are good tracers of galactic populations. We present a study of 41,034 MSTO and subgiant stars from the GALAH survey. Using a…
The spatial distribution of satellites in galaxy clusters
Qing Gu, Qi Guo, Tianchi Zhang +4
The planar distributions of satellite galaxies around the Milky Way and Andromeda have been extensively studied as potential challenges to the standard cosmological model. Using th…
A spectroscopic study of blue supergiant stars in Local Group spiral galaxies: Andromeda and Triangulum
Cheng Liu, Rolf-Peter Kudritzki, Gang Zhao +4
Low-resolution LAMOST and Keck spectra of blue supergiant stars distributed over the disks of the Local Group spiral galaxies M 31 and M 33 are analyzed to determine stellar effect…
