CSST large-scale structure analysis pipeline: IV. Cosmic Voids Identified from Galaxy Group Samples as Probes of the Large-scale Structure
Yingxiao Song, Xiaohu Yang, Yan Gong +16
Because groups are directly associated with halos, they allow for considerably simpler theoretical modeling than approaches based on individual galaxies. We therefore propose to us…
Lyman- forest constraints on pure and mixed fuzzy dark matter
Jianxiang Liu, Yan Gong, Xingchen Zhou
Fuzzy dark matter (FDM), often realized as an ultralight scalar field, can suppress the growth of small-scale structures and could be strictly tested with Lyman- forest measurem…
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 th…
Detecting dark matter substructure with lensed quasars in optical bands
Jianxiang Liu, Kai Liao, Yan Gong
Flux ratios of multiple images in strong gravitational lensing systems provide a powerful probe of dark matter substructure. Optical flux ratios of lensed quasars are typically aff…
Improving Photometric Redshift Estimation for CSST Mock Catalog Using SED Templates Calibrated with Perturbation Algorithm
Yicheng Li, Liping Fu, Zhu Chen +11
Photometric redshifts of galaxies obtained by multi-wavelength data are widely used in photometric surveys because of its high efficiency. Although various methods have been develo…
Cosmological distance forecasts for the CSST Galaxy Survey using BAO peaks
Feng Shi, Jieyi Tian, Zhejie Ding +21
The measurement of cosmological distances using baryon acoustic oscillations (BAO) is crucial for studying the universe's expansion. The Chinese Space Station Telescope (CSST) gala…
