Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
The Fate of the Milky Way--Andromeda System: To Merge or Not?
Hao Wu, Yang Huang, Huawei Zhang +2
It has long been predicted that the Milky Way (MW) will eventually merge with Andromeda (M31), a view reinforced by \textit{HST} measurements indicating a small M31 transverse velo…
Revisiting the Proper Motions of M31 and M33 Using Massive Supergiant Stars with Gaia DR3
Hao Wu, Yang Huang, Huawei Zhang +1
The proper motions (PMs) of M31 and M33 are key to understanding the Local Group's dynamical evolution. However, measurement discrepancies between Gaia blue and red samples, regard…
Finding Quasars Behind the Galactic Plane: Spectroscopic Identifications of ~1300 New Quasars at |b|<=20 degree from LAMOST DR10
Zhi-Ying Huo, Yuming Fu, Yang Huang +10
Quasars behind the Galactic plane (GPQs) are excellent tracers to probe the chemistry and kinematics of the interstellar/intergalactic medium (ISM/IGM) of the Milky Way along sight…
The LAMOST Spectroscopic Survey of Supergiants in M31 and M33
Hao Wu, Yang Huang, Huawei Zhang +3
We present systematic identifications of supergiants of M31/M33 based on massive LAMOST spectroscopic survey. Radial velocities of nearly 5000 photometrically selected M31/M33 supe…
