Constraining and Comparing the Dynamical Dark Energy and f(R) Modified Gravity Models with Cosmological Distance Measurements
Shuai Feng, Yan Gong, Xiaohui Liu +2
We constrain and compare the CDM dynamical dark energy model and three modified gravity models using the current cosmological distance measurements, including 11…
CSST Strong Lensing Preparation: Cosmological constraints from double-source-plane strong lensing systems in era of CSST
Bei-Chen Wu, Xiaoyue Cao, Nan Li +5
Double source plane strong lensing (DSPL) systems offer a robust, independent probe of cosmological parameters. The Chinese Space Station Telescope (CSST) is expected to discover h…
Exploring Cosmological Constraints of the Void-Lensing Cross-Correlation in the CSST Photometric Survey
Qi Xiong, Yan Gong, Junhui Yan +8
We investigate the cosmological constraints from the void-lensing cross-correlation assuming the CDM model for the Chinese Space Station Survey Telescope (CSST) photometric surv…
Forecasting the Constraint on the Hu-Sawicki Modified Gravity in the CSST pt Photometric Survey
Jun-Hui Yan, Yan Gong, Qi Xiong +5
We forecast the constraint on the Hu-Sawicki model from the photometric survey operated by the Chinese Space Station Survey Telescope (CSST). The simulated pt data…
Future Cosmology: New Physics and Opportunity from the China Space Station Telescope (CSST)
Yan Gong, Haitao Miao, Xingchen Zhou +12
The China Space Station Telescope (CSST) is the next-generation Stage~IV survey telescope. It can simultaneously perform multi-band imaging and slitless spectroscopic wide- and dee…
