Observations of Orbiting Hot Spots around Naked Singularities
Yiqian Chen, Peng Wang, Haitang Yang
Recently, it has been reported that photons can traverse naked singularities in the Janis-Newman-Winicour and Born-Infeld spacetimes when these singularities are appropriately regu…

Gravitational Lensing by Transparent Janis-Newman-Winicour Naked Singularities
Deyou Chen, Yiqian Chen, Peng Wang +2
The Janis-Newman-Winicour (JNW) spacetime can describe a naked singularity with a photon sphere that smoothly transforms into a Schwarzschild black hole. Our analysis reveals that…
