Possible formation of wormholes from dark matter in an isothermal galactic halo and void
Nayan Sarkar, Susmita Sarkar, Farook Rahaman +2
It is well known that traversable wormholes are valid solutions of the Einstein field equations, but these structures can only be maintained by violating the null energy condition.…
FLRW viscous cosmological models
G. S. Khadekar, Saibal Ray, X. -H. Meng
In this paper we solve Friedmann equations by considering a universal media as a non-perfect fluid with bulk viscosity and is described by a general "gamma law" equation of state o…
Kantowski-Sachs Universe in the Varying Speed of Light Theory
G. S. Khadekar, Arti Ghogre, Saibal Ray
In this work we consider the Kantowski-Sachs (KS) universe in the framework of varying speed of light theory. We present the general solutions of the gravitational field equations…
Charged Perfect Fluid Sphere in Higher Dimensional Spacetime
Piyali Bhar, Tuhina Manna, Farook Rahaman +2
Present paper provides a new model for perfect fluid sphere filled with charge in higher dimensional spacetime admitting conformal symmetry. We consider a linear equation of state…
Brane Kantowski-Sachs Universe with Linear Equation of State and Future Singularity
G. S. Khadekar
We consider the brane Kantowski-Sachs universe when bulk space is five dimensional anti-de Sitter obeying a linear equation of state of the form , where $ γ,\:p_{0}…
Noncommutative geometry inspired wormholes with conformal motion
Farook Rahaman, Saibal Ray, G. S. Khadekar +2
This paper discusses a new wormhole solution that admits conformal motion, given a noncommutative-geometry background. After a discussion of the wormhole geometry and the energy co…
