What Prevents Resolving the Hubble Tension through Late-Time Expansion Modifications?
Zhihuan Zhou, Zhuang Miao, Sheng Bi +2
We demonstrate that Type Ia supernovae (SNe Ia) observations impose the critical constraint for resolving the Hubble tension through late-time expansion modifications. Applying the…
Testing the effect of on tension using a Gaussian Process method
En-Kun Li, Minghui Du, Zhi-Huan Zhou +2
Using the redshift space distortion (RSD) data, the tension is studied utilizing a parameterization of growth rate . Here, is derive…
Inflation in the general Poincaré gauge cosmology
Hongchao Zhang, Lixin Xu
The general Poincaré gauge cosmology given by a nine-parameter gravitational Lagrangian with ghost- and tachyon-free conditions is studied from the perspective of field theory. By…
Late-time acceleration and inflation in a Poincaré gauge cosmological model
Hongchao Zhang, Lixin Xu
A self-consistent model which can unify Starobinsky inflation and the CDM model in the framework of Poincaré gauge cosmology (PGC) is studied in this work, without extra inflato…
Poincaré Gauge Gravity Cosmology
Hongchao Zhang, Lixin Xu
In this work, we construct the logical framework of the Poincaré gauge gravity cosmology based on five postulations, and introduce the modified redshift relation within this framew…
