Guide for the Hubble Tension: Mid-Time Solutions and Generalized PAge Parameterizations
Jing-Yi Jia, Da-Chun Qiang, Hao Wei
In cosmology, the Hubble tension has become one of the most serious challenges in the last decade. Assuming that all the observational data are right, one of the ways out is to mod…
Revisiting the equation of state of dark energy from DESI BAO with SNe Ia and CMB
Jie Zheng, Da-Chun Qiang, Zhi-Qiang You +1
The Dark Energy Spectroscopic Instrument (DESI) measurements of baryon acoustic oscillations (BAO) have recently shown a mild preference for dynamical dark energy over the standard…
From Nonparametric Distance Reconstruction to Testing the Etherington Relation and Cosmic Curvature Using 2D and 3D BAO Measurements
Darshan Kumar, Jie Zheng, Zhi-Qiang You +1
We present a joint test of cosmic curvature, , and the cosmic distance-duality relation (CDDR) using the Etherington relation, which connects the luminosity and angular dia…
The impact of 2D and 3D BAO measurements on the Cosmic Distance Duality Relation with HII galaxies
Jie Zheng, Da-Chun Qiang, Zhi-Qiang You +1
The cosmic distance duality relation (CDDR) is a fundamental and practical condition in observational cosmology that connects the luminosity distance and angular diameter distance.…
New Insights into Dark Energy from DESI DR2 with CMB and SNIa
Da-Chun Qiang, Jing-Yi Jia, Hao Wei
Analyses by the Dark Energy Spectroscopic Instrument (DESI) collaboration suggest a significant deviation from the CDM model when their baryon acoustic oscillation (BAO) measure…
Cosmological constraints on dark energy models using DESI BAO 2024
Jie Zheng, Da-Chun Qiang, Zhi-Qiang You
Recently, the measurements of baryon acoustic oscillations (BAO) by the Dark Energy Spectroscopic Instrument (DESI) indicate a potential deviation from the standard CDM model. S…
