Generalised Hayward spacetimes: Geometry, matter and scalar quasinormal modes
Poulami Dutta Roy, Sayan Kar
Bardeen's 1968 idea of a regular black hole spacetime was revived by Hayward in 2006 through the construction of a new example of such a geometry. Later it was realised by Neves an…

A simple analytic example of the gravitational wave memory effect
Indranil Chakraborty, Sayan Kar
We report an analytical example of the gravitational wave memory effect in exact plane wave spacetimes. A square pulse profile is chosen which gives rise to a curved wave region sa…

Wormholes with a warped extra dimension?
Sayan Kar
We investigate the role of a specifically warped extra dimension in constructing examples of higher dimensional spacetimes representing Lorentzian wormholes. The warping chosen is…
