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…
Inferring the mass content of galaxy clusters with satellite kinematics and Jeans Anisotropic modeling
Rui Shi, Wenting Wang, Zhaozhou Li +7
Satellite galaxies can be used to indicate the dynamical mass of galaxy groups and clusters. In this study, we apply the axis-symmetric Jeans Anisotropic Multi-Gaussian Expansion J…
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…
