The effects of the orbital configurations of mergers on reshaping galaxy structures
Xinyi Wu, Ling Zhu, Jiang Chang +2
We performed a systematic analysis of how the orbital configuration of a merger can influence the structural formation of remnant galaxies using 531 merger pairs selected from Illu…
The Shape and Mass of the Galactic Dark Matter Halo from the Axisymmetric Jeans Model
Lan Zhang, Xiang-Xiang Xue, Ling Zhu +8
We explore the density profile, shape, and virial mass of the Milky Way's dark matter halo using K giants (KG) from LAMOST and SDSS/SEGUE, as well as blue horizontal branch (BHB) s…
The warm-hot intergalactic medium in inter-cluster filaments -- A forecast for HUBS observations based on eRASS1 superclusters
Yuanyuan Zhao, Haiguang Xu, Ang Liu +8
Cosmological simulations indicate that nearly half of the baryons in the nearby Universe are in the warm-hot intergalactic medium (WHIM) phase, and about a half them reside in cosm…
Uncovering the first-infall history of the LMC through its dynamical impact in the Milky Way halo
Yanjun Sheng, Yuan-Sen Ting, Xiang-Xiang Xue +2
The gravitational interactions between the LMC and the Milky Way cause dynamical perturbations in the MW halo, leading to biased distributions of stellar density and kinematics. We…
