ELUCID-DESI II. Revealing dark matter mass, tidal, and velocity (MTV) fields using galaxy group phase information
Qingyang Li, Xiaohu Yang, Wensheng Hong +24
We introduce a novel method for reconstructing the cosmic mass, tidal, and velocity (MTV) fields over the redshift range using the phase information of galaxy groups.…
Dark energy perturbations and the robustness of cosmological neutrino-mass constraints
Yu-Hang Yang, Emmanuel N. Saridakis, Yi-Fu Cai +1
Cosmological observations are placing increasingly stringent bounds on the sum of neutrino masses, approaching the lower limits implied by neutrino oscillation experiments. Recent…
Linking Electron Density with Elevated Star Formation Activity from to
Sijia Li, Si-Yue Yu, Luis C. Ho +7
The interstellar medium (ISM) in high-redshift galaxies exhibits significantly higher electron densities () than in the local universe. To investigate the origin of this…
Cosmological Simulations with Massive Neutrinos: Efficiency and Accuracy
Bing-Hang Chen, Jun-Jie Zhao, Hao-Ran Yu +3
Constraining neutrino mass through cosmological observations relies on precise simulations to calibrate their effects on large scale structure, while these simulations must overcom…
The Jiutian simulations for the CSST extra-galactic surveys
Jiaxin Han, Ming Li, Wenkang Jiang +23
We provide an overview of the Jiutian simulations, a hybrid simulation suite for the China Space Survey Telescope (CSST) extragalactic surveys. It consists of four complementary mo…
Probing vector chirality in the early Universe
Junsup Shim, Ue-Li Pen, Hao-Ran Yu +1
We explore the potential of using late-time galaxy spins to test the parity symmetry of primordial vector fossils. Using -body simulations, we analyze halo spins as a reliable p…
Enhancing Morphological Measurements of Cosmic Web with Delaunay Tessellation Field Estimation
Yu Liu, Yu Yu, Pengjie Zhang +1
The density fields constructed by traditional mass assignment methods are susceptible to irritating discreteness, which hinders morphological measurements of cosmic large-scale str…
