Kerr--Newman Memory Effect
Marco Galoppo, Rudeep Gaur, Christopher Harvey-Hawes
We bring the Kerr--Newman spacetime into the Bondi--Sachs gauge by means of zero angular momentum, null geodesics. We compute the memory effect produced at the black hole horizon b…
The Kerr Memory Effect at Null Infinity
Rudeep Gaur
We compute the memory effect due to a gravitational wave striking a Kerr black hole as seen by an observer at null infinity. This is done by working in Bondi--Sachs coordinates. It…
Black holes embedded in FLRW cosmologies
Rudeep Gaur, Matt Visser
There has recently been some considerable interest expressed in a highly speculative model of black hole evolution -- allegedly by a postulated direct coupling between black holes…
Defect wormholes are defective
Joshua Baines, Rudeep Gaur, Matt Visser
The various "defect wormholes" developed by Klinkhamer have recently attracted considerable attention -- especially in view of the fact that the simplest example, the so-called "va…
