Wormhole Solutions in Modified Brans-Dicke Theory
Eleftherios Papantonopoulos, Christoforos Vlachos
We consider a modified Brans-Dicke theory in which except the usual Brans-Dicke parameter a new dimensionful parameter appears which modifies the kinetic term of the scalar field c…
Exact charged black hole solutions in D-dimensions in f(R) gravity
Zi-Yu Tang, Bin Wang, Eleftherios Papantonopoulos
We consider Maxwell-f(R) gravity and obtain an exact charged black hole solution with dynamic curvature in D-dimensions. Considering a spherically symmetric metric ansatz and witho…
Strong Cosmic Censorship in Horndeski Theory
Kyriakos Destounis, Rodrigo D. B. Fontana, Filipe C. Mena +1
The strong cosmic censorship hypothesis has recently regained a lot of attention in charged and rotating black holes immersed in de Sitter space. Although the picture seems to be c…
Quasinormal modes of three-dimensional rotating Hořava AdS black hole and the approach to thermal equilibrium
Ramón Bécar, P. A. González, Eleftherios Papantonopoulos +1
We compute the quasinormal modes (QNMs) of a massive scalar field in the background of a rotating three-dimensional Hořava AdS black hole, and we analyze the effect of the breaking…
Strong Cosmic Censorship in higher-dimensional Reissner-Nordström-de Sitter spacetime
Hang Liu, Ziyu Tang, Kyriakos Destounis +3
It was recently shown that Strong Cosmic Censorship might be violated for near-extremally-charged black holes in 4-dimensional de Sitter space under scalar perturbations. Here, we…
Instability of Reissner-Nordström-AdS black hole under perturbations of a scalar field coupled to Einstein tensor
E. Abdalla, B. Cuadros-Melgar, R. D. B. Fontana +3
We study the instability of a Reissner-Nordström-AdS (RNAdS) black hole under perturbations of a massive scalar field coupled to Einstein tensor. Calculating the potential of the s…
