Signatures of Novikov-Thorne accretion disks around rotating black holes in semiclassical gravity with trace anomaly
Yuxiang Zuo, Shiyang Hu, Dan Li +3
Semiclassical gravity provides a promising framework to address the black hole singularity problem through quantum backreaction characterized by a coupling parameter, making it ess…

Influence of the external electromagnetic field on the properties of the Novikov-Thorne accretion disk in Kerr spacetime
Shiyang Hu, Yuxiang Zuo, Dan Li +1
The Novikov-Thorne accretion disk model is widely employed in astrophysics, yet computing its blackbody spectrum theoretically requires analytical expressions for the orbital param…

Shadows of three black holes in static equilibrium configuration
Dan Li, Yuxiang Zuo, Shiyang Hu +3
In this paper, we employ a ray-tracing algorithm to simulate the shadows of three equal-mass black holes in static equilibrium across a wide parameter space. We find that the shado…
