A parameterized equation of state for dark energy and Hubble Tension
Jing-Ya Zhao, Tong-Yu He, Jia-Jun Yin +2
We propose a parameterized equation of state for dark energy and perform observational tests with the Hubble parameter measurements, the Pantheon supernova sample, baryon acoustic…

Observational properties of black hole in quantum fluctuation modified gravity
Jiajun Yin, Tong-Yu He, Ming Liu +4
This study investigates the properties of the thin accretion disk around a black hole in quantum fluctuation modified gravity (QFMGBH) using the Novikov-Thorne model. We restrict t…

Reconstructing square-law k-inflation from Planck data
Ming Liu, Tong-Yu He, Bohai Chen +2
We explore a square-law k-inflation using the Hamilton-Jacobi approach. Focusing on scenarios where the Hubble parameter exhibits a power-law dependence on the k-field, our analysi…
