Memory Effect of Gravitational Wave Pulses in PP-Wave Spacetimes
Sucheta Datta, Sarbari Guha
In this paper, we study the gravitational memory effect in pp-wave spacetimes due to the passage of a pulse having the form of a ramp profile through this spacetime. We have analyz…
Memory Effect of Plane Gravitational Wave Pulses
Sucheta Datta, Sarbari Guha, Deeshani Mitra
A gravitational wave pulse, while passing through spacetime, brings about a change in the relative separation between free particles. This `memory effect' serves as one of the sign…
On the propagation of gravitational waves in matter-filled Bianchi I universe
Sucheta Datta, Sarbari Guha, Samarjit Chakraborty
In this paper we apply the Regge-Wheeler formalism to study the propagation of axial and polar gravitational waves in matter-filled Bianchi I universe. Assuming that the expansion…
Propagation of Axial and Polar Gravitational Waves in Kantowski-Sachs Universe
Sucheta Datta, Sarbari Guha
We apply the Regge-Wheeler formalism to study axial and polar gravitational waves in Kantowski-Sachs universe. The background field equations and the linearised perturbation equati…
Axial Gravitational Waves in Bianchi I Universe
Sarbari Guha, Sucheta Datta
In this paper, we have studied the propagation of axial gravitational waves in Bianchi I universe using the Regge-Wheeler gauge. In this gauge, there are only two non-zero componen…
Propagation of Gravitational Waves in Anisotropic Universe
Sucheta Datta, Sarbari Guha
In this paper, we have considered a toy model of an anisotropic universe and studied the propagation of gravitational waves in such a universe. The consideration of this toy model…
