First Observational Evidence for Split Infall Flow of Cosmic Filaments into Clusters
Ji Yao, Huanyuan Shan, Pengjie Zhang +5
Velocity fields in the cosmic web are fundamental to structure formation but remain difficult to observe directly beyond the linear regime. Here we present observational evidence t…
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…
BioArc: Discovering Optimal Neural Architectures for Biological Foundation Models
Yi Fang, Haoran Xu, Jiaxin Han +4
Foundation models have revolutionized various fields such as natural language processing (NLP) and computer vision (CV). While efforts have been made to transfer the success of the…
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…
Assessing subhalo finders in cosmological hydrodynamical simulations
Victor J. Forouhar Moreno, John Helly, Robert McGibbon +5
Cosmological simulations are essential for inferring cosmological and galaxy population properties based on forward-modelling, but this typically requires finding the population of…
