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…
Phase Space Distribution Functions and Energy Distributions of Dark Matter Particles in Haloes
Axel Gross, Zhaozhou Li, Yong-Zhong Qian
For a spherical dark matter halo with isotropic velocity distribution, the phase space distribution function (DF), the energy distribution, and the density profile form a set of se…
Efficient Formation of Massive Galaxies at Cosmic Dawn by Feedback-Free Starbursts
Avishai Dekel, Kartick S. Sarkar, Yuval Birnboim +2
JWST observations indicate a surprising excess of luminous galaxies at and above, consistent with efficient conversion of the accreted gas into stars, unlike the suppres…
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…
