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…

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…
