Resolving the Hubble Tension in the Early Dark Energy Framework with JWST and DESI Data
Guo-Hong Du, Tian-Nuo Li, Lu Yin +4
In the JWST and DESI era, the JWST high-redshift galaxy observations and DESI baryon acoustic oscillation (BAO) measurements severely challenge the standard CDM model, while the…
Constraining the Potential Index of the Early Dark Energy Model Using Cosmic Birefringence from Planck and ACT
Kedi Zhang, Lu Yin
Cosmic birefringence and the Hubble tension represent compelling challenges to the standard CDM model. The early dark energy (EDE) model with potentials $V(ϕ) \propto [1-\cos(ϕ/…
How much has DESI dark energy evolved since DR1?
Eoin Ó Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari +1
DESI has reported a dynamical dark energy (DE) signal based on the CDM model that is in conflict with Hubble tension. Recalling that the combination of DESI DR1 BAO and DR…
Do high redshift QSOs and GRBs corroborate JWST?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Lu Yin
The James Webb Space Telescope (JWST) is reporting massive high redshift galaxies that appear challenging from the CDM perspective. Interpreted as a cosmological problem, this n…
