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…
