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…
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…
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…
Revisiting progenitor-age dependence of type Ia supernova luminosity standardization process
Junchao Wang, Zhiqi Huang, Lu Huang
Much of the research in supernova cosmology is based on an assumption that the peak luminosity of type Ia supernovae (SNe Ia), after a standardization process, is independent of th…
Redshift Evolution and Non-Universal Dispersion of Quasar Luminosity Correlation
Zhuoyang Li, Lu Huang, Junchao Wang
The standard CDM model is recently reported to deviate from the high-redshift Hubble diagram of type Ia supernovae (SNe) and quasars (QSOs) at confidence level. In this…
The Tension in Light of Updated Redshift-Space Distortion Data and PAge Approximation
Lu Huang, Zhiqi Huang, Huan Zhou +1
One of the most prominent challenges to the standard Lambda cold dark matter (CDM) cosmology is the tension between the structure growth parameter constrained by the cosmi…
Search for lensing signatures from the latest fast radio burst observations and constraints on the abundance of primordial black holes
Huan Zhou, Zhengxiang Li, Kai Liao +5
The possibility that primordial black holes (PBHs) form a part of dark matter has been considered for a long time but poorly constrained over a wide mass range. Fast radio bursts (…
A More Accurate Parameterization based on cosmic Age (MAPAge)
Lu Huang, Zhiqi Huang, Zhuoyang Li +1
Recently, several statistically significant tensions between different cosmological datasets have raised doubts about the standard Lambda cold dark matter (CDM) model. A recent…
Constraints on the abundance of primordial black holes with different mass distributions from lensing of fast radio bursts
Huan Zhou, Zhengxiang Li, Zhiqi Huang +2
Primordial black holes (PBHs) has been considered to form a part of dark matter for a long time but the possibility has been poorly constrained over a wide mass range, including th…
Reconciling low and high redshift GRB luminosity correlations
Lu Huang, Zhiqi Huang, Xiaolin Luo +2
The correlation between the peak spectra energy () and the equivalent isotropic energy () of long gamma-ray bursts (GRBs), the so-called Amati relation, is often…
Reaffirming the Cosmic Acceleration without Supernova and CMB
Xiaolin Luo, Zhiqi Huang, Qiyue Qian +1
Recent discussions about supernova magnitude evolution have raised doubts about the robustness of the late-universe acceleration. In a previous letter, Huang did a null test of the…
Can Non-standard Recombination Resolve the Hubble Tension?
Miaoxin Liu, Zhiqi Huang, Xiaolin Luo +3
The inconsistent Hubble constant values derived from cosmic microwave background (CMB) observations and from local distance-ladder measurements may suggest new physics beyond the s…
