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…
Completing the Penrose Process without a Horizon
Yang Huang, Shiyang Hu, Bin Chen +1
In its standard black-hole realization, the Penrose process uses an event horizon to remove a negative-energy fragment. We show that, at the kinematic level, horizon absorption can…
Construction of an analytic multi-component accretion environment and its application to Kerr black hole imaging
Shiyang Hu, Dan Li, Chen Deng +2
The construction of accretion environments is fundamental to black hole imaging. From a purely geometric perspective, we construct a novel analytic accretion environment comprising…
Rational Orbits and Gravitational Waves in Static Spherical Spacetimes: An Open-Source Numerical Framework
Dan Li, Shiyang Hu, Chen Deng +2
Timelike orbits constitute a crucial probe for exploring the intrinsic properties of curved spacetimes, and the carried gravitational radiation signals provide a direct window into…
Reshaping the inner shadow of a Kerr black hole by a torn accretion disk
Shiyang Hu, Dan Li, Chen Deng +1
When an accretion flow extends to the event horizon, their intersection defines the contour of the inner shadow. However, the morphological evolution of this critical feature remai…
Gravitational emissions and light curves of quasi-periodic orbits in Schwarzschild spacetime embedded in a Dehnen-type dark matter halo
Shijie Tan, Chunhua Jiang, Dan Li +3
Timelike orbits in curved spacetimes encode intrinsic information about the background geometry and serve as critical probes for investigating gravitational theories and source dis…
