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…
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…
Unraveling the Complexity of Dwarf Galaxy Dynamics: A study of Binary Orbital Motions
Wenting Wang, Ling Zhu, Yipeng Jing +8
We investigate the impact of binary orbital motions on the dynamical modeling of dwarf galaxies with intrinsic line-of-sight velocity dispersions () of 1 to 9 km/s. Using…
Is the core-cusp problem a matter of perspective: Jeans Anisotropic Modeling against numerical simulations
Wenting Wang, Ling Zhu, Zhaozhou Li +14
Mock member stars for 28 dwarf galaxies are constructed from the cosmological Auriga simulation, which reflect the dynamical status of realistic stellar tracers. The axis-symmetric…
A machine learning approach to infer the accreted stellar mass fractions of central galaxies in the TNG100 simulation
Rui Shi, Wenting Wang, Zhaozhou Li +5
We propose a random forest (RF) machine learning approach to determine the accreted stellar mass fractions () of central galaxies, based on various dark matter halo…
What to expect from dynamical modelling of cluster haloes I. The information content of different dynamical tracers
Qingyang Li, Jiaxin Han, Wenting Wang +3
Using hydrodynamical simulations, we study how well the underlying gravitational potential of a galaxy cluster can be modelled dynamically with different types of tracers. In order…
