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…
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…
Observed Anti-parallel Correlation Between Spiral Galaxy and Cosmic Filament Spins
Hao-da Wang, Peng Wang, Min Bao +7
Understanding the origin of galactic angular momentum and its connection to the cosmic web remains a pivotal issue in galaxy formation. Using kinematic data from the MaNGA survey,…
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…
Connection Between SDSS Galaxies and ELUCID Subhaloes in the Eye of Machine Learning
Xiaoju Xu, Xiaohu Yang, Haojie Xu +1
We explore the feasibility of learning the connection between SDSS galaxies and ELUCID subhaloes with random forest (RF). ELUCID is a constrained -body simulation constructed us…
Galaxy-halo size relation from Sloan Digital Sky Survey Data Release 7 and the ELUCID simulation
Youcai Zhang, Xiaohu Yang, Hong Guo
Based on galaxies in the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) and dark matter haloes in the dark matter only, cosmological and constrained ELUCID simulation, we inves…
