Corotating binary systems of identical Kerr-Newman black holes
Cabrera Munguia, Roberto Ivan (2020-11-05)In the present paper binary configurations of identical corotating Kerr-Newman black holes separated by a massless strut are derived and studied. After solving the axis conditions and establishing the absence of magnetic ... -
Corotating dyonic binary black holes
Cabrera Munguia, Roberto Ivan (2020-11-12)This paper is dedicated to derive and study binary systems of identical corotating dyonic black holes separated by a massless strut—two 5-parametric corotating binary black hole models endowed with both electric and magnetic ... -
Energy extraction in electrostatic extreme binary black holes
Cabrera Munguia, Roberto Ivan (2022-12-28)Relying on the Penrose process mechanism, we study the possibility of energy extraction from a binary system composed of two extreme electrostatic black holes (BHs) oppositely charged, separated by a strut described by ... -
Extreme binary black holes in a physical representation
Cabrera Munguia, Ivan (2018-10-31)Stationary axisymmetric binary systems of unequal co- and counter-rotating extreme Kerr black holes separated by a conical singularity are studied. Both solutions are identified as two three- parametric subfamilies of the ... -
Geodesics of Hayward black hole surrounded by quintessence
Cabrera Munguia, Roberto Ivan (2021-02-26)Basing on the ideas used by Kiselev, we study the Hayward black hole surrounded by quintessence. The values critical of mass and the normalization factor are obtained. We also described the horizons and the extremal ... -
Metric for two unequal extreme Kerr-Newman black holes
Cabrera Munguia, Roberto Ivan (2022-01-12)In the present paper, within the framework of stationary axisymmetric spacetimes, binary systems composed of two unequal co- and counter-rotating extreme Kerr-Newman black holes separated by a massless strut are reported. ... -
Quasinormal modes of the Hayward black hole surrounded by quintessence: Scalar, electromagnetic and gravitational perturbations
Pedraza, Omar (2022-04-20)In this paper, we study the quasinormal modes for scalar, electromagnetic, and gravita- tional axial perturbations in the Hayward regular black hole surrounded by quintessence (HBH-ωq). Using the third-order WKB approximation, ... -
Soluciones axial simétricas estáticas de sistemas binarios en 5D
Cabrera Munguia, Roberto Ivan (2021-07-05)Usando una solución esta ́tica axial simétrica que describe un sistema binario de agujeros negros idénticos en un espacio-tiempo en cuatro dimensiones (4D), construimos y estudiamos a través de la estructura de barras, una ... -
The relations between the multipole moments in axistationary electrovacuum spacetimes and the N-soliton solution
Cabrera Munguia, Roberto Ivan; Costa Filho, Etevaldo dos Santos; Costa Filho, Etevaldo dos Santos; guimarães, Angelo (2022-01-27)A general formulation of the relativistic multipole moments in axistationary electrovac spacetimes is introduced in a closed analytical form. We give a complete description of how the Ernst potentials on the symmetry axis ... -
Unequal binary configurations of interacting Kerr black holes
Cabrera Munguia, Ivan (2018-11-10)Stationary axisymmetric binary configurations of unequal Kerr sources with a massless strut among them are developed in a physical representation. In order to describe interacting black holes, the axis conditions in the ...
