Sumarna Haroon,Sumarna Haroon,Mubasher Jamil,Mubasher Jamil,Kimet Jusufi,Kai Lin,Kai Lin,Robert B. Mann +7 more
TL;DR: In this article, the effects of dark matter on the shadow of a rotating black hole in the background of perfect dark matter fluid, along with its extension to nonzero cosmological constant, were investigated.
Journal ArticleDOI
Black hole surrounded by a dark matter halo in the M87 galactic center and its identification with shadow images
TL;DR: In this paper, the authors presented 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 curve (URC) dark matter profile representing family of spiral galaxies.
Journal ArticleDOI
Thermodynamics of Gauss-Bonnet-de Sitter black holes
TL;DR: In this article, the authors investigated the thermodynamics of Gauss-Bonnet black holes in asymptotically de Sitter spacetimes embedded in an isothermal cavity, via a Euclidean action approach.
Journal ArticleDOI
Shadow Images of a Rotating Dyonic Black Hole with a Global Monopole Surrounded by Perfect Fluid
TL;DR: In this article, the authors revisited the rotating global monopole metric and extended the metric to a rotating dyonic global monopoles in the presence of a perfect fluid and showed that the surface topology at the event horizon is a 2-sphere using the Gauss-Bonnet theorem.
Journal ArticleDOI
Shadow Images of a Rotating Dyonic Black Hole with a Global Monopole Surrounded by Perfect Fluid
TL;DR: In this paper, the authors revisited and extended the prior work of Filho and Bezerra to rotating dyonic global monopoles in presence of a perfect fluid, and showed that the surface topology at the event horizon is a 2- sphere using the Gauss-Bonnet theorem.
