Topologically Charged Morris-Thorne-type Wormholes and the Energy Conditions
Faizuddin Ahmed, Md Sabir Ali, Adnan Malik
In this paper, we investigate topologically charged Morris-Thorne-type traversable wormholes by solving the Einstein field equations with an anisotropic fluid as the energy-momentu…
Photon orbits and phase transition for Letelier AdS black holes immersed in perfect fluid dark matter
Ashima Sood, Md Sabir Ali, J. K. Singh +1
We obtain an exact solution of spherically symmetric Letelier AdS black holes immersed in perfect fluid dark matter (PFDM). Considering the cosmological constant as the positive pr…
Lyapunov Exponents and Phase Structure of Lifshitz and Hyperscaling Violating Black Holes
A. Naveena Kumara, Shreyas Punacha, Md Sabir Ali
We study the phase structure of hyperscaling violating black holes using Lyapunov exponents. For describing hyperscaling violating system, we chose a particular gravity model const…
Thermodynamics of Kerr-Sen-AdS black holes in the restricted phase space
Md Sabir Ali, Sushant G. Ghosh, Anzhong Wang
We analyse the restricted phase space thermodynamics (RPST) of Kerr-Sen-AdS black holes with the central charge and its conjugate chemical potential but exclude the familia…
Stationary black holes and stars in the Brans-Dicke theory with revisited
Md Sabir Ali, Sourav Bhattacharya, Shagun Kaushal
It was shown a few years back that for a stationary regular black hole or star solution in the Brans-Dicke theory with a positive cosmological constant , endowed with a de Sitte…
Rotating regular black holes in AdS spacetime and its shadow
Balendra Pratap Singh, Md Sabir Ali, Sushant~G. ~Ghosh
The presence of a photon region around the black hole is an essential feature in receiving the emitted spectrum from the vicinity of the black hole by the distant observer. In this…
