Gravitational lensing and deflection angles of generalised Ellis-Bronnikov wormhole embedded in a warped braneworld background
Soumya Jana, Vivek Sharma, Suman Ghosh
We investigate null trajectories, deflection angles, and gravitational lensing in the spacetime of generalized Ellis-Bronnikov (GEB) wormholes and their embedding in a five-dimensi…

Gravitational wave radiation from periodic orbits in regular black holes
Rishav Agrawal, Anjan Kar, Soumya Jana +1
Gravitational wave radiation from periodic orbits in some standard regular black hole spacetimes is studied, primarily using known methods (numerical and analytic). We demonstrate…

New rotating Lorentzian wormhole spacetime
Anjan Kar, Soumya Jana, Sayan Kar
A rotating version of a known static, spherically symmetric, zero Ricci scalar Lorentzian wormhole is constructed. It turns out that for this given non-rotating geometry, the stand…
