Raychaudhuri Equation and Weyl-Driven Shear: A Weak-Field Approach to Lensing and Gravitational Waves
Madhukrishna Chakraborty, Subenoy Chakraborty
The letter studies phenomena like gravitational wave propagation and gravitational lensing using the celebrated Raychaudhuri equation (RE) in the weak field limit. Newtonian analog…
Accelerating scaling solutions from dark matter particle creation
Sudip Halder, Jaume de Haro, Supriya Pan +3
This article opens new window to obtain accelerating scaling attractors without any need of dark energy. We study cosmological dynamics in a two-fluid system where pressureless dar…
Quasinormal modes and Grey body factors of Wormholes: From General prescription to Einstein Gauss Bonnet realizations
Madhukrishna Chakraborty, Subenoy Chakraborty
Traversable wormholes are one of the most exciting predictions of General Relativity that offer short-cuts through space-time. However, their feasibility requires the violation of…
Wormholes: Myth or Reality? Prospects for Future Observations
Subenoy Chakraborty, Madhukrishna Chakraborty
Traversable wormholes (TWHs) remain one of the most intriguing predictions of General Relativity (GR), offering passage through space-time. However, their existence requires the vi…
Classical and Quantum cosmology for two scalar field Brans-Dicke type theory: A Noether Symmetry approach
Shriton Hembrom, Roshni Bhaumik, Sourav Dutta +1
The paper deals with a cosmological model containing two scalar fields which can be considered as an extension of the Brans-Dicke scalar field model. Due to highly coupled non line…
Exploring Traversable Wormholes in gravity: Shadows and Quasinormal modes
Madhukrishna Chakraborty, Subenoy Chakraborty
The present work deals with some WH solutions in gravity theory for non-constant red-shift function subject to a power law model of , being the non-metricity scala…
