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…
An Optimal In-Situ Multipole Algorithm for the Isotropic Three-Point Correlation Functions
Wenjie Ju, Longlong Feng, Zhiqi Huang +2
We present an optimised multipole algorithm for computing the three-point correlation function (3PCF), tailored for application to large-scale cosmological datasets. The algorithm…
MUltiplexed Survey Telescope (MUST) Science White Paper I: Overview of Large-Scale Structure Cosmology in the Era of Stage-V Spectroscopic Surveys
Cheng Zhao, Song Huang, Mengfan He +41
The MUltiplexed Survey Telescope (MUST) is a 6.5-meter telescope under development. Dedicated to highly-multiplexed, wide-field spectroscopic surveys, MUST observes over 20,000 tar…
Pair Counting without Binning -- A New Approach to Correlation Functions in Clustering Statistics
Shiyu Yue, Longlong Feng, Wenjie Ju +6
This paper presents a novel perspective on correlation functions in the clustering analysis of the large-scale structure of the universe. We first recognise that pair counting in b…
Curvature perturbations from kinetic preheating after -attractor inflation
Zhiqi Huang, Xichang Ouyang, Yu Cui +7
Preheating at the end of inflation is a violent nonlinear process that efficiently transfers the energy of the inflaton to a second field, the preheat field. When the preheat field…
Key drivers of the preference for dynamic dark energy
Zhiqi Huang, Jianqi Liu, Jianfeng Mo +9
Joint analysis of the baryon acoustic oscillations (BAO) measurement by the Dark Energy Spectroscopic Instrument (DESI) first data release, Type Ia supernovae (SNe) of the Dark Ene…
