Probing Primordial Chirality in the Matter Distribution
Fang-Na Shao, Hao-Ran Yu, Ming-Jie Sheng +2
Whether parity symmetry was violated in the early universe remains one of the fundamental open questions in cosmology. If so, it may leave an intrinsic handedness in the large-scal…
CUBE2: A Parallel -Body Simulation Code for Scalability, Accuracy, and Memory Efficiency
Hao-Ran Yu, Bing-Hang Chen, Kun Xu +4
-body simulation serves as a critical method for modeling cosmic evolution and poses a significant challenge in high-performance computing. We present CUBE2, an open-source cosm…
A high-significance detection of primordial tidal torque imprints
Ming-Jie Sheng, Hao-Ran Yu, Min Bao +8
Tidal-torque theory predicts that galaxy angular momenta are imprinted by the primordial tidal field acting on proto-structures and that they can retain information about the early…
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…
