Physical Implications and Updated Observational Constraints of the PAge-like Unified Dark Fluid Model
Yan Su, Zhiqi Huang, Yanhong Yao +2
The standard paradigm of cosmology assumes two distinct dark components, namely dark matter and dark energy. However, the necessity of splitting the dark-side world into two sector…
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…
Quantifying the tension between cosmological models and JWST red candidate massive galaxies
Junchao Wang, Zhiqi Huang, Lu Huang +1
We develop a Python tool to estimate the tail distribution of the number of dark matter halos beyond a mass threshold and in a given volume in a light-cone. The code is based on th…
A PAge-like Unified Dark Fluid Model
Junchao Wang, Zhiqi Huang, Yanhong Yao +3
The unified dark fluid model unifies dark matter and dark energy into a single component, providing an alternative and more concise framework for interpreting cosmological observat…
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…
