A class of conserved currents for linearized gravity in the Kerr spacetime
Alexander M. Grant, Éanna É. Flanagan
We construct a class of conserved currents for linearized gravity on a Kerr background. Our procedure, motivated by the current for scalar fields discovered by Carter (1977), is gi…
Persistent gravitational wave observables: Nonlinear plane wave spacetimes
Éanna É. Flanagan, Alexander M. Grant, Abraham I. Harte +1
In the first paper in this series, we introduced "persistent gravitational wave observables" as a framework for generalizing the gravitational wave memory effect. These observables…
Angular momentum at null infinity in Einstein-Maxwell theory
Béatrice Bonga, Alexander M. Grant, Kartik Prabhu
On Minkowski spacetime, the angular momentum flux through null infinity of Maxwell fields, computed using the stress-energy tensor, depends not only on the radiative degrees of fre…
Conserved currents for electromagnetic fields in the Kerr spacetime
Alexander M. Grant, Éanna É. Flanagan
We construct a variety of conserved currents for test electromagnetic fields on a Kerr background. Our procedure, which involves the symplectic product for electromagnetism and sym…
