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…

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…

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…

Galaxy and halo properties around cosmic filaments from Sloan Digital Sky Survey Data Release 7 and the ELUCID simulation

Youcai Zhang, Xiaohu Yang, Hong Guo +2

Using galaxies from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) along with haloes from the dark matter only constrained ELUCID (Exploring the Local Universe with the reC…

Statistical properties of filaments in the cosmic web

Youcai Zhang, Hong Guo, Xiaohu Yang +1

In the context of the cosmological and constrained ELUCID simulation, this study explores the statistical characteristics of filaments within the cosmic web, focussing on aspects s…

The origin of lopsided satellite galaxy distribution around isolated systems in MillenniumTNG

Yikai Liu, Peng Wang, Hong Guo +4

Dwarf satellites in galaxy groups are distributed in an anisotropic and asymmetric manner, which is called the ``lopsided satellite distribution''. This lopsided signal has been ob…

The boundary of cosmic filaments

Wei Wang, Peng Wang, Hong Guo +12

For decades, the boundary of cosmic filaments have been a subject of debate. In this work, we determine the physically-motivated radii of filaments by constructing stacked galaxy n…

The Beyond-Halo Mass Effects of the Cosmic Web Environment on Galaxies

Kuan Wang, Camille Avestruz, Hong Guo +2

Galaxy properties primarily depend on their host halo mass. Halo mass, in turn, depends on the cosmic web environment. We explore if the effect of the cosmic web on galaxy properti…
