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…
Effectiveness of halo and galaxy properties in reducing the scatter in the stellar-to-halo mass relation
Wenxiang Pei, Qi Guo, Shi Shao +2
The stellar-to-halo mass relation (SHMR) is a fundamental relationship between galaxies and their host dark matter haloes. In this study, we examine the scatter in this relation fo…
Simulating emission line galaxies for the next generation of large-scale structure surveys
Wenxiang Pei, Qi Guo, Ming Li +8
We investigate emission line galaxies across cosmic time by combining the modified L-Galaxies semi-analytical galaxy formation model with the JiuTian cosmological simulation. We im…
JWST's first glimpse of a z > 2 forming cluster reveals a top-heavy stellar mass function
Hanwen Sun, Tao Wang, Ke Xu +11
Clusters and their progenitors (protoclusters) at z = 2-4, the peak epoch of star formation, are ideal laboratories to study the formation process of both the clusters themselves a…
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…
A younger Universe implied by satellite pair correlations from SDSS observations of massive galaxy groups
Qing Gu, Qi Guo, Marius Cautun +5
Many of the satellites of galactic-mass systems such as the Miky Way, Andromeda and Centaurus A show evidence of coherent motions to a larger extent than most of the systems predic…
