Quasinormal Modes of Black Holes Surrounded by Dark Matter and Their Connection with the Shadow Radius
Kimet Jusufi
The purpose of this article is twofold. First, we highlight a simple connection between the real part of quasinormal modes (QNMs) in the eikonal limit and shadow radius of BHs and…
Rotating regular black holes in conformal massive gravity
Kimet Jusufi, Mubasher Jamil, Hrishikesh Chakrabarty +3
In this paper, we use a suitable conformal rescaling to construct static and rotating regular black holes in conformal massive gravity. The new metric is characterized by the mass…
Higher order corrections to deflection angle of massive particles and light rays in plasma media for stationary spacetimes using the Gauss-Bonnet theorem
Gabriel Crisnejo, Emanuel Gallo, Kimet Jusufi
The purpose of this article is twofold. First, we extend the results presented in [Gabriel Crisnejo and Emanuel Gallo, Phys.Rev.D 97, 124016 (2018)] to stationary spacetimes. Speci…
Deflection angle of charged massive particles in slowly rotating Kerr-Newman space-times via Gauss-Bonnet theorem and Hamilton-Jacobi method
Kimet Jusufi
In this paper the problem of gravitational deflection of relativistic charged massive particles in slowly rotating Kerr-Newman black holes is considered. Toward this purpose we hav…
Shadows and deflection angle of charged and slowly rotating black holes in Einstein-Æther theory
Tao Zhu, Qiang Wu, Mubasher Jamil +1
In this paper, we study the shadow cast by two types of charged and slowly rotating black holes in Eisntein-aether theory of gravity. This two types of black holes are correspondin…
Black Hole Surrounded by a Dark Matter Halo in the M87 Galactic Center and its Identification with Shadow Images
Kimet Jusufi, Mubasher Jamil, Paolo Salucci +2
In this paper we present a new black hole solution surrounded by dark matter halo in the galactic center using the mass model of M87 and that coming from the Universal Rotation Cur…
Shadow Images of a Rotating Dyonic Black Hole with a Global Monopole Surrounded by Perfect Fluid
Sumarna Haroon, Kimet Jusufi, Mubasher Jamil
In this paper we revisit and extend the prior work of Filho and Bezerra [Phys. Rev D, 64, 084009 (2001)] to rotating dyonic global monopoles in presence of a perfect fluid. We then…
On the possibility of wormhole formation in the galactic halo due to dark matter Bose-Einstein condensates
Kimet Jusufi, Mubasher Jamil, Muhammad Rizwan
It has been recently claimed that dark matter could be in the form of a Bose-Einstein condensate (BEC) in order to explain the dynamics at large distances from the galactic center…
Distinguishing a Kerr-like black hole and a naked singularity in perfect fluid dark matter via precession frequencies
Muhammad Rizwan, Mubasher Jamil, Kimet Jusufi
We study a Kerr-like black hole and naked singularity in perfect fluid dark matter (PFDM). The critical value of spin parameter is presented to differentiate the black hole f…
