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 regularized. In this paper, we investigate observational signatures of hot spots orbiting these naked singularities, with a focus on discerning them from black holes. In contrast to Schwarzschild black holes, we unveil the presence of multiple additional image tracks within critical curves in time integrated images capturing a complete orbit of hot spots. Moreover, these new images manifest as a more pronounced second-highest peak in temporal magnitudes when observed at low inclinations.

  1. Rotating Black Holes in Einstein-Born-Infeld Theory

    gr-qc 2025-07 conditional novelty 7.0 of 10

    Exact rotating charged Einstein-Born-Infeld black holes are constructed numerically; they show charge-dependent extremal or naked-singularity endpoints, gyromagnetic ratio above 2, and ISCO radii below Kerr-Newman values.
