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…
Narrowing down the Hubble tension to the first two rungs of distance ladders
Lu Huang, Rong-Gen Cai, Shao-Jiang Wang +2
The decade-persistent Hubble tension has become a crisis of modern cosmology between the early-Universe extrapolation from globally fitting the standard CDM to Planck-CMB…
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…
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…
