Weak Cosmic Censorship: As Strong as Ever
Shahar Hod
Spacetime singularities that arise in gravitational collapse are always hidden inside of black holes. This is the essence of the weak cosmic censorship conjecture. The hypothesis,…
Bounds on the mass-to-radius ratio for non-compact field configurations
Shahar Hod
It is well known that a spherically symmetric compact star whose energy density decreases monotonically possesses an upper bound on its mass-to-radius ratio, . Howeve…
Analytic Study of Rotating Black-Hole Quasinormal Modes
Uri Keshet, Shahar Hod
A Bohr-Sommerfeld equation is derived for the highly-damped quasinormal mode frequencies omega(n>>1) of rotating black holes. It may be written as 2\int_C(p_r+ip_0)dr=(n+1/2)h, whe…
Asymptotic quasinormal mode spectrum of rotating black holes
Shahar Hod
Motivated by novel results in the theory of black-hole quantization, we study {\it analytically} the quasinormal modes (QNM) of ({\it rotating}) Kerr black holes. The black-hole os…
Cosmic Censorship: the Role of Quantum Physics
Shahar Hod
The cosmic censorship hypothesis introduced by Penrose thirty years ago is still one of the most important open questions in {\it classical} general relativity. The main goal of th…
Universal Upper Bound to the Entropy of a Charged System
Shahar Hod
We derive a universal upper bound to the entropy of a charged system. The entropy bound follows from application of the generalized second law of thermodynamics to a gedanken exper…
