Black holes with dark matter halos and a positive cosmological constant: Energy conditions and signatures
Long-Yue Li, Li-Ming Cao, Yungui Gong +3
We study static, spherically symmetric black holes surrounded by dark matter halos in the presence of a positive cosmological constant. Assuming vanishing radial pressure, we deriv…
Exceptional lines of Reissner-Nordström-de Sitter black hole surrounded by a thin shell of matter
Liang-Bi Wu, Yu-Sen Zhou, Ming-Fei Ji +3
We study the exceptional line (EL) in the quasinormal modes (QNMs) of Reissner-Nordström-de Sitter black hole surrounded by a static thin shell of matter. For a conformally scalar…
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…
The appearance of de Sitter black holes and strong cosmic censorship
Li-Ming Cao, Long-Yue Li, Xia-Yuan Liu +1
We study the optical appearance of Schwarzschild-de Sitter and Reissner-Nordström-de Sitter black holes viewed by distant observers inside cosmological horizons. Unlike their asymp…
The appearance of the regular black hole with a stable inner horizon
Li-Ming Cao, Long-Yue Li, Xia-Yuan Liu +1
The strong cosmic censorship conjecture, which states that the evolution of generic initial data will always produce a globally hyperbolic spacetime, is hard to be tested by astron…
