Evolution of the stellar mass function in open clusters from a universal and unsegregated initial state
Lu Li, Zhaozhou Li, Zhengyi Shao +2
The stellar mass function (MF) and its spatial variation (mass segregation) within star clusters encode signatures of early formation physics and subsequent secular evolution. Yet,…
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…
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…
Scaling Relations in the Phase-Space Structure of Dark Matter Haloes
Axel Gross, Zhaozhou Li, Yong-Zhong Qian
We present new scaling relations for the isotropic phase-space distribution functions (DFs) and energy distributions of simulated dark matter haloes. These relations are inspired b…
Why artificial disruption is not a concern for current cosmological simulations
Feihong He, Jiaxin Han, Zhaozhou Li
Recent studies suggest that cold dark matter subhalos are hard to disrupt and almost all cases of subhalo disruption observed in numerical simulations are due to numerical effects.…
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…
