Non-exotic traversable wormholes with strong deflection angle in King and Dekel-Zhao dark matter halos under f(R,Lm) gravity
Susmita Sarkar, Nayan Sarkar, Abdelmalek Bouzenada +1
In this article, we investigate asymptotically flat non-exotic traversable wormhole geometries within the King and Dekel-Zhao dark matter halos in the framework of grav…
Deflection of light by dark matter supporting traversable wormholes in the framework of Kalb-Ramond gravity
Susmita Sarkar, Nayan Sarkar
This study explores the possible formation of asymptotically flat traversable wormholes within dark matter halos under the framework of Kalb-Ramond gravity. The wormhole solutions…
Yukawa-Casimir wormholes within Einstein-Cartan gravity framework
Nayan Sarkar, Susmita Sarkar, Abdelmalek Bouzenada
The Einstein-Cartan (EC) theory of gravity provides a natural extension of general relativity by incorporating spacetime torsion to account for the intrinsic spin of matter. In thi…
Deflection Angle of Regular Black Holes in Nonlinear Electrodynamics: Gauss-Bonnet Theorem, Time Delay, Shadow, and Greybody Bound
Susmita Sarkar, Nayan Sarkar, Hasrat Hussian Shah +2
In this article, we study the weak gravitational lensing in the background of regular, static, spherically symmetric black hole solutions of Einstein's standard general relativity…
Relativistic compact stars coupled with dark energy in Heintzmann spacetime
Susmita Sarkar, Nayan Sarkar
The literature suggests that dark energy is responsible for the accelerating expansion of the universe due to its negative pressure, therefore, dark energy can be used as a possibl…
Study on deflection angle, shadow, quasinormal modes, and greybody factor of the black hole surrounded by quintessence in Rastall gravity
Susmita Sarkar, Nayan Sarkar, Tuhina Manna +2
The present study focuses on investigating the deflection angle in the weak-field approximation, shadow, quasinormal modes using Lyapunov exponents, and lower bound of the greybody…
