Decoding the Gravitational Geometry and Stellar Photometric Profiles of Galaxy NGC 7331
Aritra Sanyal Bikramarka S. Choudhury Farook Rahaman
Galaxy rotation curves provide a powerful probe of mass distributions in spiral galaxies. We present a general relativistic analysis of NGC 7331 using its observed rotation curve a…
Exact Gravastar Solution
Farook Rahaman, Bikramarka S. Choudhury, Aritra Sanyal +2
Astrophysical black holes arise as exact solutions of the Einstein field equations. Therefore, any alternative, such as a gravastar, must satisfy the same level of mathematical rig…
Revisiting The Gravitational Mirroring In Presence of Compact Objects
Bikramarka S Choudhury, Aritra Sanyal, Md Khalid Hossain +1
We propose a novel concept of astrophysical mirroring in the schwarzschild framework, which emerges as a direct consequence of gravitational lensing effects occurring in the immedi…
Euclidean quantum wormholes
Farook Rahaman, Bikramarka S. Choudhury, Anikul Islam
We study wormhole as the solution of the Wheeler-deWitt (WdW ) equation satisfying Hawking-Page wormhole boundary conditions in Friedmann-Robertson-Walker (FRW) cosmology. The quan…
Catenoid Inspired Hyperbolic Wormhole Geometry
Bikramarka S Choudhury, Md Khalid Hossain, Farook Rahaman
We unveil a novel class of traversable wormholes exhibiting exact spherical symmetry, geometrically inspired by the minimal surface structure of a catenoid. Introducing the spaceti…
Evolving wormhole geometry from dark matter energy density
Farook Rahaman, Bikramarka S Choudhury
We analyze traversable wormholes defined by the dynamic line elements that asymptotically approaches Friedmann-Robertson-Walker (FRW) universe. This dynamical wormholes is supporte…
