OCTOPUS: A Versatile, User-Friendly, and Extensible Public Code for General-Relativistic Ray-Tracing in Spherically Symmetric and Static Spacetimes
Shiyang Hu, Shijie Tan, Dan Li +3
This paper presents OCTOPUS, a relativistic ray-tracing algorithm developed within a Fortran-based, OpenMP-accelerated framework, designed for asymptotically flat, spherically symm…
Light Curves of Chaotic Charged Hot-Spots in Curved Spacetime: Opening an Observational Window to Chaos
Shiyang Hu, Dan Li, Chen Deng
The observed scarcity of chaotic phenomena in astronomy contrasts sharply with their theoretical significance, primarily due to the absence of a robust framework for detecting chao…
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…
