Hermes - Towards an Optimal High-Performance Algorithm for Cosmic Statistics of Large Data Sets
Long-long Feng, Tengpeng Xu, Tian-Cheng Luan +7
We present Hermes, an in situ multiresolution framework for efficient and flexible measurements of cosmic large-scale-structure statistics from discrete catalogues. Hermes reconstr…
Universal Fitting Formulae for the Peak Concentration of Dark Matter Halos
Dao-zhou Wang, Weipeng Lin, Tian-Cheng Luan
The prediction of the structural properties of dark matter halos is crucial for studies in modern cosmology and galaxy formation. Utilizing a comprehensive suite of N-body simulati…
Impact of cosmic web on the properties of galaxies in IllustrisTNG simulations
Guangyao Yu, Weishan Zhu, Qi-Rui Yang +3
We investigate the influence of the cosmic web on galaxy properties in the IllustrisTNG simulations. To disentangle the effects of galaxy groups and cosmic filaments, we classify t…
Recovering Cosmic Structure with a Simple Physical Constraint
Tian-Cheng Luan, Xin Wang, Jiacheng Ding +3
Radio observation of the large-scale structure (LSS) of our Universe faces major challenges from foreground contamination, which is many orders of magnitude stronger than the cosmi…
Restoring Missing Modes of 21cm Intensity Mapping with Deep Learning: Impact on BAO Reconstruction
Qian Li, Xin Wang, Xiaodong Li +3
In 21cm intensity mapping of the large-scale structure (LSS), regions in Fourier space could be compromised by foreground contamination. In interferometric observations, this conta…
