"A study of gravitational wave memory effects in radiative geometries and wormholes "

Indranil Chakraborty , IIT Kharagpur
[Host: David Nichols]

Gravitational memory effects are persistent deformations caused due to the passage of a gravitational wave pulse. It is a nonlinear effect in General Relativity that remains yet to be detected. In this talk, primarily from a theoretical perspective, we study memory effects in two different settings: i) Radiative geometries, ii) Lorentzian wormholes. In radiative geometries, we show how geodesic and geodesic deviation equations encode the gravitational wave memory. In the latter case, we perform a Bondi-Sachs analysis and try to show how the Bondi mass loss depends on the wormhole hair.
