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…
Model-independent determination of cosmic curvature based on Padé approximation
Shi-Yu Li, Yun-Long Li, Tong-Jie Zhang +1
Given observations of the standard candles and the cosmic chronometers, we apply Padé parameterization to the comoving distance and the Hubble paramter to find how stringent the co…
Model Comparison of Dark Energy models Using Deep Network
Shi-Yu Li, Yun-Long Li, Tong-Jie Zhang
This work uses a combination of a variational auto-encoder and generative adversarial network to compare different dark energy models in light of observations, e.g., the distance m…
Utility of observational Hubble parameter data on dark energy evolution
Xiao-Lei Meng, Xin Wang, Shi-Yu Li +1
Aiming at exploring the nature of dark energy, we use thirty-six observational Hubble parameter data (OHD) in the redshift range to make a cosmologic…
Model-independent determination of curvature parameter by using and data pair from BAO measurement
Yun-Long Li, Shi-Yu Li, Tong-Jie Zhang +1
We present a model-independent determination of the curvature parameter by using the Hubble parameter and angular diameter distance from the recent baryon aco…
