Shadows and precession of orbits in rotating Janis-Newman-Winicour spacetime

Understand

In this paper, we construct the rotating Janis-Newman-Winicour (JNW) naked singularity spacetime using Newman-Janis Algorithm (NJA).

• We analyse NJA with and without complexification methods and find that the energy conditions do satisfied when we skip the complexification step.
• We study the shadows cast by rotating JNW naked singularity and compare them with the shadows cast by the Kerr black hole.
• We find that the shadow of the rotating naked singularity can be distinguished from the shadow of the Kerr black hole.
