Motion of spinning particles around a quantum-corrected black hole without Cauchy horizons

Jiawei Chen, Jinsong Yang

In this paper, we investigate the motion of spinning particles around a covariant quantum-corrected black hole without a Cauchy horizon within the framework of effective quantum gr…

Periodic orbits and gravitational waveforms in quantum-corrected black hole spacetimes

Jiawei Chen, Jinsong Yang

In this paper, we study the periodic orbits of massive particles around two quantum-corrected black holes proposed in effective quantum gravity, and explore the quantum gravity eff…

Investigating shadow of a rotating charged black hole with a cosmological constant immersed in the perfect fluid dark matter

Zheng-Long Ban, Xiao-Jun Gao, Jinsong Yang

In this paper, we mainly investigate the shadow of a rotating charged black hole with a cosmological constant immersed in perfect fluid dark matter. We first obtain the charged sph…

Shadows and optical appearance of quantum-corrected black holes illuminated by static thin accretions

Jiawei Chen, Jinsong Yang

Recently, two new quantum-corrected black hole models satisfying covariance have been proposed within the framework of effective quantum gravity. In this paper, we study how the qu…
