Gravitational memory effect

WebMar 12, 2024 · We study the displacement memory effect and its connection with the extended-BMS symmetries near the horizon of black holes. We show there is a permanent shift in the geodesic deviation vector relating two nearby timelike geodesics placed close to the horizon of black holes, upon the passage of gravitational waves.

WebNov 9, 2024 · We consider the gravitational ``memory effect'' for linearized perturbations off of Minkowski space in odd dimensional spacetimes of dimension D greater than or equal to 3 by examining the effects of gravitational radiation from point particle scattering on the relative separation of test particles to leading order in 1/r. We also compute ... WebJan 1, 2024 · We compute the memory effect produced at the black hole horizon by a transient gravitational shock wave. As shown by Hawking, Perry, and Strominger (HPS) such a gravitational wave produces a deformation of the black hole geometry which from future null infinity is seen as a Bondi-Metzner-Sachs supertranslation. lewis university student activities https://teecat.net

Gravitational wave memory and its tail in cosmology

Gravitational memory effects, also known as gravitational-wave memory effects are predicted persistent changes in the relative position of pairs of masses in space due to the passing of a gravitational wave. Detection of gravitational memory effects has been suggested as a way of validating Einstein's … See more The effect should, in theory, be detectable by recording changes in the distance between pairs of free-falling objects in spacetime before and after the passage of gravitational waves.
