Spin-induced Scalar Clouds around Kerr-Newman Black Holes

Guangzhou Guo, Peng Wang, Tianshu Wu +1

Recent studies have demonstrated that a scalar field non-minimally coupled to the electromagnetic field can experience a spin-induced tachyonic instability near Kerr-Newman black h…

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…

Stationary Scalar Clouds around Kerr-Newman Black Holes

Guangzhou Guo, Peng Wang, Tianshu Wu +1

This study investigates scalar clouds around Kerr-Newman black holes within the Einstein-Maxwell-scalar model. Tachyonic instabilities are identified as the driving mechanism for s…

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…
