A cosmic filament catalog for COSMOS-Web Data Release 1 across 0.5 < z < 3.5
Qiaoyang Hao, Tao Wang, Weishan Zhu +4
Cosmic filaments represent the environments in which most galaxies form and evolve. However, the spatial distribution of filaments and the link between galaxy properties and their…
Observational Evidence for the Kinematic Memory of Cosmic Filaments from Satellite Orbital Orientations
Peng Wang, Wei Wang, Wenting Wang +5
We present an observational study of the kinematic coherence between satellite orbital planes and the cosmic web. Using the SDSS DR12 galaxy sample combined with the Bisous filamen…
Multi-tracer mass bias in matched cosmic voids from SDSS DR7 and the ELUCID constrained simulation
Youcai Zhang, Xiaohu Yang, Hong Guo +1
Cosmic voids provide a unique environment for studying the relationship between galaxies, subhaloes, and dark matter in the underdense Universe. Using the SDSS galaxy catalogue and…
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…
Robustness of cosmic void statistics: insights from SDSS DR7 and the ELUCID simulation
Youcai Zhang, Xiaohu Yang, Hong Guo +2
We present a systematic analysis of the statistical properties of cosmic voids using galaxies from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) and subhaloes from the ELU…
