Letter: Charged Black Hole Solutions in Einstein-Born-Infeld Gravity with a Cosmological Constant
Sharmanthie Fernando,Don Krug +1 more
TL;DR: In this paper, the causal structure of these solutions differs drastically from their counterparts in Einstein-Maxwell gravity with a cosmological constant, and the charged de-Sitter black holes can have up to three horizons and the charge anti-de Sitter black hole can have one or two depending on the parameters chosen.

Journal ArticleDOI
Thermodynamics of Born-Infeld-anti-de Sitter black holes in the grand canonical ensemble
TL;DR: In this article, the authors studied the thermodynamics and stability of static electrically charged Born-Infeld black holes in AdS space in D = 4 and derived the Gibbs free energy, entropy and specific heat of the black holes.
Journal ArticleDOI
Quasinormal modes of the Bardeen black hole: Scalar perturbations
Sharmanthie Fernando,Juan Correa +1 more
TL;DR: In this article, a thorough analysis of the quasinormal modes of the Bardeen black hole due to scalar perturbations was performed by varying the charge and mass of the field.
Journal ArticleDOI
Schwarzschild black hole surrounded by quintessence: null geodesics
TL;DR: In this paper, the null geodesics of the Schwarzschild black hole surrounded by quintessence matter are studied and exact solutions are presented in terms of Jacobi-elliptic integrals for all possible energy and angular momentum of the photons.
