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…

Establishing HI mass v.s. stellar mass and halo mass scaling relations using an abundance matching method

Yi Lu, Xiaohu Yang, Chengze Liu +5

We combined data from the Sloan Digital Sky Survey (SDSS) and the Arecibo Legacy Fast ALFA Survey (ALFALFA) to establish the HI mass vs. stellar mass and halo mass scaling relation…

FEASTS Combined with Interferometry (II): Significantly Changed HI Surface Densities and Even More Inefficient Star Formation in Galaxy Outer Disks

Jing Wang, Xuchen Lin, Lister Staveley-Smith +12

We update the HI surface density measurements for a subset of 17 THINGS galaxies by dealing with the short-spacing problem of the original VLA HI images. It is the same sample that…

Modeling the Nonlinear Power Spectrum in Low-redshift HI Intensity Mapping

Zhixing Li, Laura Wolz, Hong Guo +2

We present a simulation-based framework to forecast the HI power spectrum on non-linear scales (), as measured by interferometer arrays like MeerKAT in…

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…

CSST large-scale structure analysis pipeline: I. constructing reference mock galaxy redshift surveys

Yizhou Gu, Xiaohu Yang, Jiaxin Han +29

In this paper, we set out to construct a set of reference mock galaxy redshift surveys (MGRSs) for the future Chinese Space-station Survey Telescope (CSST) observation, where subse…
