The Universal Specific Merger Rate of Dark Matter Halos
Fuyu Dong, Donghai Zhao, Jiaxin Han +3
We employ a set of high resolution N-body simulations to study the merger rate of dark matter halos. We define a specific merger rate by normalizing the average number of mergers p…
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…
The outermost edges of the Milky Way halo from galaxy kinematics
Zhao-Zhou Li, Jiaxin Han
We measure for the first time the outermost edges of the Milky Way (MW) halo in terms of the depletion and turnaround radii. The inner depletion radius, , identified…
The stellar mass in and around isolated central galaxies: connections to the total mass distribution through galaxy-galaxy lensing in the Hyper Suprime-Cam survey
Wenting Wang, Xiangchong Li, Jingjing Shi +7
Using photometric galaxies from the HSC survey, we measure the stellar mass density profiles for satellite galaxies as a function of the projected distance, , to isolated cent…
