Probing Primordial Chirality in the Matter Distribution
Fang-Na Shao, Hao-Ran Yu, Ming-Jie Sheng +2
The authors develop a helicity‑based estimator to detect handedness in the large‑scale matter distribution as a signature of primordial parity violation, test it on simulations wit…
Local Nonlinear Transforms Effectively Extract Cosmological Information From Large-Scale Structure
Yun Wang, Hao-Ran Yu, Yu Yu +1
Extracting cosmological information from nonlinear and non-Gaussian large-scale structure remains a major challenge. We introduce the (Zel'dovich-inspired) ZI transform, a simple o…
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 +9
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…
