Challenging the weak cosmic censorship conjecture with charged quantum particles
(Amer Physical SocCollege PkEUA, 2011)
Chaos and fractals in geodesic motions around a nonrotating black hole with halos
(American Physical SocCollege PkEUA, 2000)
Evolution of perturbations of squashed Kaluza-Klein black holes: Escape from instability
(AMER PHYSICAL SOC, 2008)
The squashed Kaluza-Klien (KK) black holes differ from the Schwarzschild black holes with asymptotic flatness or the black strings even at energies for which the KK modes are not excited yet, so that squashed KK black holes ...
BTZ gems inside regular Born-Infeld black holes
(IOP Publishing, 2020-09)
The regular black hole solution arising as a spherically symmetric vacuum solution of Born-Infeld gravity possesses an asymptotic interior structure which is very well described by a four-dimensional generalization of the ...
Scattering of massless scalar waves by Reissner-Nordstrom black holes
(AMER PHYSICAL SOC, 2009)
We present a study of scattering of massless planar scalar waves by a charged nonrotating black hole. Partial wave methods are applied to compute scattering and absorption cross sections, for a range of incident wavelengths. ...
Self-gravitating black hole scalar wigs
(American Physical Society, 2017-07-26)
It has long been known that no static, spherically symmetric, asymptotically flat Klein-Gordon scalar field configuration surrounding a nonrotating black hole can exist in general relativity. In a series of previous papers, ...
Quasistationary solutions of self-gravitating scalar fields around black holes
(2015)
Recent perturbative studies have shown the existence of long-lived, quasistationary configurations of scalar fields around black holes. In particular, such configurations have been found to survive for cosmological time ...
Gravitational lensing by a Horndeski black hole
(Springer, 2017-11)
In this article we study gravitational lensing by non-rotating and asymptotically flat black holes in Horndeski theory. By adopting the strong deflection limit, we calculate the deflection angle, from which we obtain the ...
