Detection of gamma-ray burst Amati relation based on Hubble data set and Pantheon+ samples
Yufen Han, Jiaze Gao, Gang Liu +1
Using gamma-ray bursts as standard candles for cosmological parameter constraints rely on their empirical luminosity relations and low-redshift calibration. In this paper, we exami…

Mitigating Cosmological Tensions via Momentum-Coupled Dark Sector Model
Gang Liu, Jiaze Gao, Yufen Han +2
In this paper, we investigate the momentum coupling between early dark energy (EDE) and cold dark matter to alleviate cosmological tensions. EDE has exhibited promising efficacy in…

Coupled Dark Sector Models and Cosmological Tensions
Gang Liu, Jiaze Gao, Yufen Han +2
In this paper, we introduce two coupling models of early dark energy (EDE) and cold dark matter aimed at alleviating cosmological tensions. We utilize the EDE component in the coup…
