Cosmic Censorship and parametrized spinning black-hole geometries

Understand

The ``cosmic censorship conjecture'' asserts that all singularities arising from gravitational collapse are hidden within black holes.

• We investigate this conjecture in a setup of interest for tests of General Relativity: black hole solutions which are parametrically small deviations away from the Kerr solution.
• These solutions have an upper bound on rotation, beyond which a naked singularity is visible to outside observers.
• We study whether these (generic) spacetimes can be spun-up past extremality with point particles or accretion disks.
