Probing power spectrum enhancement at small scales with the SKA
Hourui Zhu, Bin Yue, Yidong Xu +2
The reionization process is driven by ionizing photons from dwarf galaxies in halos with virial temperature K, while minihalos whose $T_{\rm vir}\lesssim…
Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the CDM framework
Tengpeng Xu, Suresh Kumar, Yun Chen +2
We test the dynamical dark-energy CDM (CPL) framework against CDM using CMB anisotropies and lensing together with DESI DR2, SDSS-IV, transverse/angular BAO (BAOtr), and…
Dynamical Dark Energy and the Unresolved Hubble Tension: Multi-model Constraints from DESI 2025 and Other Probes
Zhuoming Zhang, Tengpeng Xu, Yun Chen
We present a Bayesian comparative analysis of five cosmological models: CDM, CDM, CDM, CDM (with scalar-field dark energy), and an interacting dark energy scenario…
CSST Strong Lensing Preparation: Cosmological Constraints Forecast from CSST Galaxy-Scale Strong Lensing
Hengyu Wu, Yun Chen, Tonghua Liu +6
Strong gravitational lensing by galaxies is a powerful tool for studying cosmology and galaxy structure. The China Space Station Telescope (CSST) will revolutionize this field by d…
Reproducing Abell 2744 with the HyperMillennium Simulation
Qiao Wang, Ming Li, Liang Gao +11
We present the Hyper Millennium (HM) simulation, an extremely large cosmological simulation designed to support next-generation galaxy surveys. The simulation follows 4.2 trillion…
Holographic dark energy in a coasting cosmology
Yunliang Ren, Xiaofeng Yang, Xuwei Zhang +5
Coasting cosmology offers an intriguing and straightforward framework for understanding the universe. In this work, we employ the Trans-Planckian Censorship Criterion (TCC) conject…
