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…

Odd-parity perturbations of trace-quadratic black holes with anisotropic matter: admissible branches, axial ringdown, and a coupled-PINN benchmark
Mushtaq Ahmad, M. Farasat Shamir, Adnan Malik +1
We study odd-parity gravitational perturbations of static black holes in trace-quadratic gravity supported by an anisotropic effective fluid with constant closure…

Cosmological bouncing solutions and their stability in teleparallel gravity
Adnan Malik, Aimen Rauf, Kazuharu Bamba +2
The cosmological dynamics in the early universe are investigated to explore the possibility of the sign reversal of the Hubble parameter as a key feature of non-singular bouncing c…
