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…
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…
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 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…
Improving the Accuracy of Halo Mass Based Statistics For Fast Approximate N-body Simulations
Yiheng Wu, Hong Guo, Volker Springel
Approximate N-body methods, such as FastPM and COLA, have been successful in modelling halo and galaxy clustering statistics, but their low resolution on small scales is a limitati…
