Periodic orbits and their gravitational wave radiations in black hole with dark matter halo
Sumarna Haroon, Tao Zhu
This study investigates the gravitational dynamics of a spherically symmetric black hole embedded within a dark matter halo, focusing on the impact of the dark matter halo on time-…
Thermodynamics of Gauss-Bonnet-de Sitter Black Holes
Sumarna Haroon, Robie A. Hennigar, Robert B. Mann +1
We investigate the thermodynamics of Gauss-Bonnet black holes in asymptotically de Sitter spacetimes embedded in an isothermal cavity, via a Euclidean action approach. We consider…
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…
Shadow and Deflection Angle of Rotating Black Holes in Perfect Fluid Dark Matter with a Cosmological Constant
Sumarna Haroon, Mubasher Jamil, Kimet Jusufi +2
The presence of dark matter around a black hole remarkably affects its spacetime. We consider the effects of dark matter on the shadow of a new solution to the Einstein equations t…
Rotating normal and phantom Einstein--Maxwell--dilaton black holes: Geodesic analysis
Mustapha Azreg-Aïnou, Sumarna Haroon, Mubasher Jamil +1
Depending on five parameters, rotating counterparts of Einstein--Maxwell--dilaton black holes are derived. We discuss their physical and geometric properties and investigate their…
