Spontaneous scalarization of Gauss-Bonnet black holes: Analytic treatment in the linearized regime
Shahar Hod
It has recently been proved that nontrivial couplings between scalar fields and the Gauss-Bonnet invariant of a curved spacetime may allow a central black hole to support spatially…
No nonminimally coupled massless scalar hair for spherically symmetric neutral black holes
Shahar Hod
We provide a remarkably compact proof that spherically symmetric neutral black holes cannot support static nonminimally coupled massless scalar fields. The theorem is based on caus…
Strong Cosmic Censorship and the Universal Relaxation Bound
Shahar Hod
The strong cosmic censorship conjecture, introduced by Penrose five decades ago, asserts that, in self-consistent theories of gravity, Cauchy horizons inside dynamically formed bla…
The quantum emission spectra of rapidly-rotating Kerr black holes: discrete or continuous?
Shahar Hod
Bekenstein and Mukhanov (BM) have suggested that, in a quantum theory of gravity, black holes may have discrete emission spectra. Using the time-energy uncertainty principle they h…
Upper bound on the gravitational masses of stable spatially regular charged compact objects
Shahar Hod
In a very interesting paper, Andréasson has recently proved that the gravitational mass of a spherically symmetric compact object of radius and electric charge is bounded f…
On the status of the hoop conjecture in charged curved spacetimes
Shahar Hod
The status and regime of validity of the famous Thorne hoop conjecture in spatially regular {\it charged} curved spacetimes are clarified.
