Signatures of the Israel Junction II: Double Photon Rings in Slowly Rotating Kerr Spacetime with Thin Shell
Long-Yue Li, Li-Ming Cao, Yungui Gong +2
Applying the junction conditions to the slowly rotating Kerr spacetime with a thin shell, when higher order terms in the spin parameter a can be neglected, we find that while the a…
Imaging Signatures of the Israel Junction: Photon Ring Evolution in Dynamical Thin Shell Schwarzschild Spacetimes
Li-Ming Cao, Long-Yue Li, Xia-Yuan Liu
We study the images of black holes by gluing two Schwarzschild spacetimes with a thin shell where the Israel junction conditions are satisfied. By studying the refraction law for n…
Images and photon regions of continuous photon sphere spacetime
Long-Yue Li, Xia-Yuan Liu, Rong-Gen Cai +2
We study images of spacetimes containing continuous photon spheres (CPS). For a self-gravitating, isotropic, spherically symmetric spacetime with CPS, we find that a thin accretion…
Image of Quantum Improved Regular Kerr Black Hole and Parameter Constraints from EHT Observations
Li-Ming Cao, Long-Yue Li, Xia-Yuan Liu
Quantum Improved Regular Kerr (QIRK) black hole is a rotating regular black hole model constructed based on the asymptotic safety method. The model eliminates the ring singularity…
