Exploring Primordial Non-Gaussianity Measurements in the CSST Spectroscopic Survey
Jiangnan Duan, Yan Gong, Qi Xiong +5
Primordial non-Gaussianity (PNG) is a fundamental probe of the physics of the early Universe and inflation. Here we present a comprehensive study of the constraints on the local-ty…
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…
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…
Cosmological Prediction from the joint observation of MeerKAT and CSST at = 0.4 1.2
Yu-Er Jiang, Yan Gong, Qi Xiong +10
Cross-correlating neutral hydrogen (HI) 21cm intensity mapping with galaxy surveys provides an effective probe of astrophysical and cosmological information. This work presents a c…
Exploring the anisotropic gravitational wave background from all-sky mock gravitational wave event catalogues
Zhencheng Li, Zhen Jiang, Yun Liu +4
Anisotropic stochastic gravitational wave background (SGWB) serves as a potential probe of the large-scale structure (LSS) of the universe. In this work, we explore the anisotropic…
Exploring cosmological constraints of the weak gravitational lensing and galaxy clustering joint analysis in the CSST photometric survey
Qi Xiong, Yan Gong, Xingchen Zhou +10
We explore the joint weak lensing and galaxy clustering analysis from the photometric survey operated by the China Space Station Telescope (CSST), and study the strength of the cos…
2D watershed void clustering for probing the cosmic large-scale structure
Yingxiao Song, Yan Gong, Qi Xiong +5
Cosmic void has been proven to be an effective cosmological probe of the large-scale structure (LSS). However, since voids are usually identified in spectroscopic galaxy surveys, t…
Void Number Counts as a Cosmological Probe for the Large-Scale Structure
Yingxiao Song, Qi Xiong, Yan Gong +6
Void number counts (VNC) indicates the number of low-density regions in the large-scale structure (LSS) of the Universe, and we propose to use it as an effective cosmological probe…
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…
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…
