Emulating the nonlinear effects of modified gravity on the matter power spectrum for reconstruction
Lanyang Yi, Kazuya Koyama, Qi Xiong +1
Including nonlinear information from modified gravity (MG) brings more constraining power to the model-independent reconstruction of MG functions. However, the calculation of the n…
Probing Baryonic Feedback Effect with CSST Weak Lensing and Future FRB Measurements
Shuai Feng, Yan Gong, Qi Xiong +4
We explore the joint probe on the baryonic feedback effect using the weak lensing measurement from the upcoming Chinese Space-station Survey Telescope (CSST) photometric survey and…
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…
The Hydrostatic Mass Bias and the Tension: A Multi-Probe Forecast for Stage-IV/V Surveys
Ayodeji Ibitoye, Prabhakar Tiwari, Qi Xiong +1
The hydrostatic mass bias () is a leading systematic uncertainty in cluster cosmology and a principal source of degeneracy with and . We investigate…
Forecasting Constraint on Primordial Black Hole Properties with the CSST pt Analysis
Dingao Hu, Yan Gong, Pengfei Su +4
This study forecasts the constraints on the properties of primordial black holes (PBHs) as a cold dark matter component using the galaxy clustering, weak lensing, and galaxy-galaxy…
Cross-Comparison of Galaxies Detected in the CSST Spectroscopic Survey and the SKA HI Survey
Yingfeng Liu, Furen Deng, Wenxiang Pei +8
We present a forward-modeling framework to forecast the galaxies detected in the Chinese Space Station Survey Telescope (CSST) spectroscopic survey and the Square Kilometre Array (…
