Cosmological neutrino N-body simulations of dark matter halo
Yu Chen, Chang-Zhi Lu, Juan Li +3
The study of massive neutrinos and their interactions is a critical aspect of contemporary cosmology. Recent advances in parallel computation and high-performance computing provide…
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…
Novel Cosmological Joint Constraints in Multidimensional Observables Space with Redshift-free Inferences
Wei Hong, Kang Jiao, Yu-Chen Wang +2
Cosmology constraints serve as a crucial criterion in discriminating cosmological models. The traditional combined method to constrain the cosmological parameters designates the co…
Kernel Selection for Gaussian Process in Cosmology: with Approximate Bayesian Computation Rejection and Nested Sampling
Hao Zhang, Yu-Chen Wang, Tong-Jie Zhang +1
Gaussian Process (GP) has gained much attention in cosmology due to its ability to reconstruct cosmological data in a model-independent manner. In this study, we compare two method…
