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…

Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the $w_{0} w_{a}$ CDM framework

Tengpeng Xu, Suresh Kumar, Yun Chen +2

We test the dynamical dark-energy $w_{0} w_{a}$ CDM (CPL) framework against $Λ$ CDM using CMB anisotropies and lensing together with DESI DR2, SDSS-IV, transverse/angular BAO (BAOtr), and…
