Polarized Image of a Synchrotron-emitting Ring in Einstein-Maxwell-scalar Theory
Yiqian Chen, Lang Cheng, Peng Wang +1
This study investigates polarized images of an equatorial synchrotron-emitting ring surrounding hairy black holes within the Einstein-Maxwell-scalar theory. Our analysis demonstrat…
Observational Signatures of Traversable Wormholes
Yiqian Chen, Lang Cheng, Peng Wang +1
In this paper, we study the observational signatures of traversable Simpson-Visser wormholes illuminated by luminous celestial spheres and orbiting hot spots. We demonstrate that w…
Distinguishing the Observational Signatures of Hot Spots Orbiting Reissner-Nordström Spacetime
Tianshu Wu, Yiqian Chen
This paper delves into observable signatures of hot spots orbiting Reissner-Nordström (RN) black holes and naked singularities. In a RN black hole case, we find two discernible len…
Observations of Orbiting Hot Spots around Scalarized Reissner-Nordström Black Holes
Yiqian Chen, Peng Wang, Haitang Yang
This paper investigates the observational signatures of hot spots orbiting scalarized Reissner-Nordström black holes, which have been reported to possess multiple photon spheres. I…
Interferometric Signatures of Black Holes with Multiple Photon Spheres
Yiqian Chen, Peng Wang, Haitang Yang
It has been reported that the photon ring structure in black hole images produces strong and universal interferometric signatures on long interferometric baselines, holding promise…
