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…

Regular hairy black holes through gravitational decoupling method
Yaobin Hua, Zhenglong Ban, Tian-You Ren +2
Within a framework requiring a well-defined event horizon and matter obeying the weak energy condition, we employ gravitational decoupling method to construct non-singular hairy bl…

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…
