Weyl transformation: a dynamical degree of freedom in the light of Dirac's Large Number Hypothesis
Prasenjit Paul, Rikpratik Sengupta, Saibal Ray
In Einstein's Field Equation(EFE) the geometry of the space-time is connected with the matter distribution. The geometry or the gravitational sector deals with classical macroscopi…
Lorentzian wormholes supported by tachyon matter
Rikpratik Sengupta, Shounak Ghosh, Mehedi Kalam
Wormholes with Ellis geometry have been successfully constructed using tachyon matter \cite{Das}. However, for such a wormhole, it is obtained that the redshift function is necessa…
Gravastar under the framework of braneworld gravity II: effect of the Kuchowicz metric function
Saibal Ray, Shounak Ghosh, Rikpratik Sengupta
In recent years, a class of compact objects called gravastars have drawn immense interest as regular solutions to end state stellar collapse. Since the energy density involved in c…
