Quantum gravity effects on particle creation and evaporation in a non-commutative black hole via mass deformation
A. A. Araújo Filho, N. Heidari, Ali Övgün
In this work, we explore a gravitational non-commutative black hole by gauging the de Sitter SO(4,1) group and employing the Seiberg-Witten map. Specifically, we examine modificati…
Thermal, topological, and scattering effects of an AdS charged black hole with an antisymmetric tensor background
H. Chen, M. Y. Zhang, A. A. Araújo Filho +2
In this study, we explore a spherically symmetric charged black hole with a cosmological constant under the influence of a Kalb--Ramond field background. We compute the photon sphe…
Shadows, greybody factors, emission rate, topological charge, and phase transitions for a charged black hole with a Kalb-Ramond field background
F. Hosseinifar, A. A. Araújo Filho, M. Y. Zhang +2
In this work, we investigate a spherically symmetric charged black hole in the presence of a Kalb--Ramond field background. We calculate the photon sphere and shadow radii and, cor…
The impact of an antisymmetric tensor on charged black holes: evaporation process, geodesics, deflection angle, scattering effects and quasinormal modes
A. A. Araújo Filho, N. Heidari, J. A. A. S. Reis +1
In this paper, we investigate the influence of anti-symmetric tensor effects, which trigger the Lorentz symmetry breaking, on charged spherically symmetric black holes. Initially,…
Gravitational lensing by a Lorentz-violating black hole
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +1
In this work, we study the gravitational lensing by a Lorentz-violating (LV) black hole inspired by the recent contribution [1]. Explicitly, we concentrate on a specific applicatio…
An exact stationary axisymmetric vacuum solution within a metric--affine bumblebee gravity
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +1
Within the framework of the spontaneous Lorentz symmetry breaking, we consider a metric--affine generalization of the gravitational sector of the Standard--Model Extension (SME), i…
Charged Black Holes with Yukawa Potential
A. A. Araújo Filho, Kimet Jusufi, B. Cuadros-Melgar +3
This study derives a novel family of charged black hole solutions featuring short- and long-range modifications. These ones are achieved through a Yukawa-like gravitational potenti…
