Degeneracy in Accretion Disk Spectra from Naked Singularities and Kerr Black Holes: Application to the AGN MCG-06-30-15
Vishva Patel, Sayantan Bhattacharya, Sudip Bhattacharyya +1
Theoretical studies suggest that gravitational collapse can form either a black hole or a visible (naked) singularity. Identifying observational signatures that distinguish these t…

Energy extraction-driven instability and horizon formation in Kerr-Newman naked singularities and their limiting cases
Vishva Patel
Energy extraction from compact objects has been a central topic in general relativity since the introduction of the Penrose process. In this work we present a unified analysis of r…
