Corrigendum to “The instability spectra of nearextremal ReissnerNordströmde Sitter black holes” [Phys. Lett. B 786 (2018) 217–222]
/ Hod, Shahar
We point out that the instability spectrum of the nearextremal ReissnerNordströmde Sitter black holes discussed in Hod (2018) [1] lies outside the superradiant regime of the system..

Upper bound on the energies of the emitted Hawking quanta
/ Hod, Shahar
Using Thorne's hoop conjecture, it is argued that the energies of the Hawking quanta emitted from canonical Schwarzschild black holes are bounded from above by the simple quantum relation E

Strong cosmic censorship in charged blackhole spacetimes: As strong as ever
/ Hod, Shahar
It is proved that dynamically formed ReissnerNordströmde Sitter (RNdS) black holes, which have recently been claimed to provide counterexamples to the Penrose strong cosmic censorship conjecture, are characterized by unstable (singular) inner Cauchy horizons. [...]

Nogo theorem for spatially regular boson stars made of static nonminimally coupled massive scalar fields
/ Hod, Shahar
We present a compact theorem which reveals the fact that static spatially regular massive scalar fields with nonminimal coupling to gravity cannot form spherically symmetric asymptotically flat horizonless matter configurations. [...]

The Reissner–Nordström black hole with the fastest relaxation rate
/ Hod, Shahar
Numerous numerical investigations of the quasinormal resonant spectra of KerrNewman black holes have revealed the interesting fact that the characteristic relaxation times τ(a¯,Q¯) of these canonical blackhole spacetimes can be described by a twodimensional function τ¯≡τ/M which increases monotonically with increasing values of the dimensionless angularmomentum parameter a¯≡J/M2 and, in addition, is characterized by a nontrivial ( non monotonic) functional dependence on the dimensionless charge parameter Q¯≡Q/M .

Lower bound on the radii of circular orbits in the extremal Kerr blackhole spacetime
/ Hod, Shahar
It is often stated in the physics literature that maximallyspinning Kerr blackhole spacetimes are characterized by nearhorizon corotating circular geodesics of radius rcircular with the property rcircular→rH+ , where rH is the horizon radius of the extremal black hole. [...]

Holographic entropy bound in higherdimensional spacetimes
/ Hod, Shahar
The celebrated holographic entropy bound asserts that, within the framework of a selfconsistent quantum theory of gravity, the maximal entropy (information) content of a physical system is given by one quarter of its circumscribing area: $S\le {S}_{\mathrm{max}}=A/4{\ell}_{P}^{2}$ (here ${\ell}_{P}$ is the Planck length).
