Plasma-Induced Modifications of the Shadows of Rotating Bardeen Black Holes with Perfect Fluid Dark Matter
Gowtham Sidharth M, Sanjit Das
We study the optical appearance of a rotating regular Bardeen black hole embedded in perfect fluid dark matter (PFDM) when photon propagation occurs through a plasma medium. Three…

Traversable Wormholes with Non-Exotic Matter: The Role of Higher Curvature Corrections
M Daniel Ranjan, Soumya Chakrabarti, Sanjit Das
In this paper, we explore wormhole solutions in a higher-derivative theory of gravity where the action depends not only on the Ricci scalar , but also on its d'Alembertian, $\Bo…

EHT-Constrained Analysis of Shadow Deformation in Quantum-Improved Rotating Non-Singular Magnetic Monopole
Gowtham Sidharth M, Sanjit Das
We studied the shadow cast by a rotating Bardeen black hole within the framework of asymptotically safe gravity. The null geodesics were analyzed using the Hamilton Jacobi separati…
