Cosmological Prediction of the Void and Galaxy Clustering Measurements in the CSST Spectroscopic Survey
Yingxiao Song, Qi Xiong, Yan Gong +10
The void power spectrum is related to the clustering of low-density regions in the large-scale structure (LSS) of the Universe, and can be used as an effective cosmological probe t…
Forecasting Constraint on the Theory with the CSST SN Ia and BAO Surveys
Jun-Hui Yan, Yan Gong, Minglin Wang +2
The modified gravity theory can explain the accelerating expansion of the late Universe without introducing dark energy. In this study, we predict the constraint strength on…
Accurately Estimating Redshifts from CSST Slitless Spectroscopic Survey using Deep Learning
Xingchen Zhou, Yan Gong, Xin Zhang +10
Chinese Space Station Telescope (CSST) has the capability to conduct slitless spectroscopic survey simultaneously with photometric survey. The spectroscopic survey will measure sli…
Reionization Parameter Inference from 3D Minkowski Functionals of the 21 cm Signals
Kangning Diao, Zhaoting Chen, Xuelei Chen +1
The Minkowski Functionals (MFs), a set of topological summary statistics, have emerged as a powerful tool for extracting non-Gaussian information. We investigate the prospect of co…
Velocity acoustic oscillations on Cosmic Dawn 21 cm power spectrum as a probe of small-scale density fluctuations
Xin Zhang, Hengjie Lin, Meng Zhang +4
We investigate the feasibility of using the velocity acoustic oscillations (VAO) features on the Cosmic Dawn 21 cm power spectrum to probe small-scale density fluctuations. In the…
Cosmological Forecast of the Void Size Function Measurement from the CSST Spectroscopic Survey
Yingxiao Song, Qi Xiong, Yan Gong +11
Void size function (VSF) contains information of the cosmic large-scale structure (LSS), and can be used to derive the properties of dark energy and dark matter. We predict the VSF…
Cosmological Prediction of the CSST Ultra Deep Field Type Ia Supernova Photometric Survey
Minglin Wang, Yan Gong, Furen Deng +3
Type Ia supernova (SN Ia) as a standard candle is an ideal tool to measure cosmic distance and expansion history of the Universe. Here we investigate the SN Ia photometric measurem…
