Prediction of Individual Halo Concentrations Across Cosmic Time Using Neural Networks
Tianchi Zhang, Tianxiang Mao, Wenxiao Xu +1
The concentration of dark matter haloes is closely linked to their mass accretion history. We utilize the halo mass accretion histories from large cosmological N-body simulations a…
Effect of Neutrinos on Angular Momentum of Dark Matter Halo
Yu Chen, Chang-Zhi Lu, Yu Lu +2
Massive neutrinos are expected to affect the large-scale structure formation, including the major component of solid substances, dark matter halos. How halos are influenced by neut…
Forecast of Cosmological Constraints with Type Ia Supernovae from the Chinese Space Station Telescope
Shi-Yu Li, Yun-Long Li, Tianmeng Zhang +5
The 2-m aperture Chinese Space Station Telescope (CSST), which observes at wavelengths ranging from 255 to 1000 nm, is expected to start science operations in 2024. An ultra-deep f…
Numerical convergence of pre-initial conditions on dark matter halo properties
Tianchi Zhang, Shihong Liao, Ming Li +1
Generating pre-initial conditions (or particle loads) is the very first step to set up a cosmological N-body simulation. In this work, we revisit the numerical convergence of pre-i…
Constraints on smoothness parameter and dark energy using observational data
Hao-Ran Yu, Tian Lan, Hao-Yi Wan +2
The universe, with large-scale homogeneity, is locally inhomogeneous, clustering into stars, galaxies and larger structures. Such property is described by the smoothness parameter…
Cosmological Constraints on the Undulant Universe
Tian Lan, Yan Gong, Hao-Yi Wan +1
We use the redshift Hubble parameter data derived from relative galaxy ages, distant type Ia supernovae (SNe Ia), the Baryonic Acoustic Oscillation (BAO) peak, and the Cosmi…
