Image of the Kerr-Newman black hole surrounded by a thin accretion disk
Sen Guo, Yu-Xiang Huang, En-Wei Liang +3
The image of a Kerr-Newman (KN) black hole (BH) surrounded by a thin accretion disk is derived. By employing elliptic integrals and ray-tracing methods, we analyze photon trajector…
Rastall gravity: accretion disk image in radiation fields context and visual transformations compared to Reissner-Nordstrom black holes
Yu-Xiang Huang, Sen Guo, Yu Liang +3
Our study investigates the astronomical implications of Rastall gravity, particularly its behavior amidst a radiation field compared to Reissner-Nordstrom (RN) black holes. Our res…
Influence of accretion disk on the optical appearance of the Kazakov-Solodukhin black hole
Yu-Xiang Huang, Sen Guo, Yu-Hao Cui +2
The optical characteristics of the Kazakov-Solodukhin (KS) black hole (BH) surrounded by a thin disk is investigated. By utilizing the ray-tracing technique, we derive the the dire…
Unveiling the unconventional optical signatures of regular black holes within accretion disk
Sen Guo, Yu-Xiang Huang, Yu-Hao Cui +4
The optical characteristics of three types of black holes (BHs) surrounded by a thin accretion disk are discussed, namely the Schwarzschild BH, Bardeen BH, and Hayward BH. We calcu…
Optical appearance of the Schwarzschild black hole in the string cloud context
Sen Guo, Yu-Xiang Huang, Guo-Ping Li
The image of a black hole (BH) consists of direct and secondary images that depend on the observer position. We investigate the optical appearance of a Schwarzschild BH in the cont…
