The tidal evolution of satellite galaxies in cosmological simulations: insights from COLIBRE
Feihong He, Jiaxin Han, Joop Schaye +12
We investigate the co-evolution of the stellar and dark matter mass of satellite galaxies using the COLIBRE cosmological hydrodynamical simulations with subhaloes resolved by the h…
The shape-velocity alignment of satellites forged by tidal locking and dynamical friction
Hao Yang, Wenting Wang, Ting S. Li +8
Utilizing the TNG50 simulation, we study two types of alignments for satellites/subhalos: 1) the alignment of their major axes with the galactocentric radial directions (radial ali…
Modelling the M68 stellar stream with realistic mass loss and frequency distributions in angle-action coordinates
Carles G. Palau, Wenting Wang, Jiaxin Han
We develop a new method for simulating stellar streams generated by globular clusters using angle-action coordinates. This method reproduces the variable mass-loss and variable fre…
Constraining the potential of the Milky Way using stellar streams and the Inverse Time Integration method
C. G. Palau, W. Wang, J. Han
We develop a method for constraining the potential of the Milky Way using stellar streams with a known progenitor. The method expresses the stream in angle-action coordinates and i…
The mass and redshift dependence of halo star clustering
Zhenlin Tan, Wenting Wang, Jiaxin He +5
We adopt the two point correlation function (2PCF) as a statistical tool to quantify the spatial clustering of halo stars, for galaxy systems spanning a wide range in host halo vir…
emPDF: Inferring the Milky Way mass with data-driven distribution function in phase space
Zhaozhou Li, Jiaxin Han, Wenting Wang +4
We introduce the emPDF (Empirical Distribution Function), a novel dynamical modeling method that infers the gravitational potential from kinematic tracers with optimal statistical…
How does the velocity anisotropy of halo stars, dark matter and satellite galaxies depend on host halo properties?
Jiaxin He, Wenting Wang, Zhaozhou Li +8
We investigate the mass () and concentration () dependencies of the velocity anisotropy () profiles for different components in the dark matter halo, including…
CSST large-scale structure analysis pipeline: I. constructing reference mock galaxy redshift surveys
Yizhou Gu, Xiaohu Yang, Jiaxin Han +29
In this paper, we set out to construct a set of reference mock galaxy redshift surveys (MGRSs) for the future Chinese Space-station Survey Telescope (CSST) observation, where subse…
Using two point correlation functions to understand the assembly histories of Milky Way-like galaxies
Yike Zhang, Wenting Wang, Jiaxin Han +4
The two point correlation function (2PCF) is a powerful statistical tool to measure galaxy clustering. Although 2PCF has also been used to study the clustering of stars on parsec a…
