Geometric obstruction to resolving the Hubble tension: orthogonality of scale and shape in distance measurements
Zhihuan Zhou, Zhuang Miao, Sheng Bi +2
We identify a geometric obstruction to resolving the Hubble tension by combining early-time sound-horizon reduction with late-time smooth dark energy. Within CDM, the BAO--SN ma…
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…
On the improved dynamics approach in loop quantum black holes
Hongchao Zhang, Wen-Cong Gan, Yungui Gong +1
In this paper, we consider the Böhmer-Vandersloot (BV) model of loop quantum black holes obtained from the improved dynamics approach. We adopt the Saini-Singh gauge, in which it w…
Cosmological Constant, Inflaton, and Dark Matter all Naturally Originated from Poincaré Gauge Gravity
Hongchao Zhang, Tao Zhu, Anzhong Wang
We propose a cosmological model in the framework of Poincaré gauge gravity, in which cosmological constant, inflaton, and dark matter candidate all naturally originate. Cosmologica…
Dirac observables in the 4-dimensional phase space of Ashtekar's variables and spherically symmetric loop quantum black holes
Geeth Ongole, Hongchao Zhang, Tao Zhu +2
In this paper, we study a proposal put forward recently by Bodendorfer, Mele and Münch and Garc\'ıa-Quismondo and Marugán, in which the two polymerization parameters of spherically…
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…
Probing the Neutrino Mass Hierarchy beyond CDM Model
En-Kun Li, Hongchao Zhang, Minghui Du +2
Taking the neutrino oscillation data into consideration, a dimensionless parameter is adopted to parameterize the three neutrino mass eigenstates and the n…
Distinguish three time-dependent dark energy models using statefinder pairs with error bars and Bayesian evidence
Hongchao Zhang, Enkun Li, Lixin Xu
In this work, two completely different approaches, statefinder with error bars and Bayesian evidence, are used to distinguish and judge three time-dependent dark energy models. The…
