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…
ELUCID-DESI I: A Parallel MPI Implementation of the Initial Condition Solver for Large-Scale Reconstruction Simulations
Wensheng Hong, Xiaohu Yang, Junde Li +10
We present a highly scalable, MPI-parallelized framework for reconstructing the initial cosmic density field, designed to meet the computational demands of next-generation cosmolog…
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…
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…
DarkAI: Reconstructing the density, velocity and tidal field of dark matter from a DESI-like bright galaxy sample
Feng Shi, Zitong Wang, Xiaohu Yang +10
Reconstructing the mass density, velocity, and tidal (MTV) fields of dark matter from galaxy surveys is essential for advancing our understanding of the LSS of the Universe. In thi…
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…
