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, and DESI DR2 dat…

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…

A new parametrization of Hubble function and Hubble tension

Tong-Yu He, Jia-Jun Yin, Zhen-Yu Wang +2

We present a new Hubble parameterization method and employ observational data from Hubble, Pantheon, and Baryon Acoustic Oscillations to constrain model parameters. The proposed me…

Possible signatures of higher dimension in thin accretion disk around brane world black hole

Ailin Liu, Tong-Yu He, Ming Liu +2

We probe deeply into the characteristics of thin accretion disk surrounding black hole within the brane world paradigm. We investigate how model parameters affect the physical prop…

Accretion of matter by a Charged dilaton black hole

Yinan Jia, Tong-Yu He, Wen-Qian Wang +2

Considering accretion onto a charged dilaton black hole, the fundamental equations governing accretion, general analytic expressions for critical points, critical velocity, critica…
