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…
