Metric Reconstruction in Kerr Spacetime

Stefan Hollands, Vahid Toomani

Metric reconstruction is the general problem of parameterizing GR in terms of its two ``true degrees of freedom'', e.g., by a complex scalar ``potential'' -- in practice mostly wit…

Spin-2 Green's Functions on Kerr in Radiation Gauge

Marc Casals, Stefan Hollands, Adam Pound +1

We construct retarded and advanced Green's functions for gravitational perturbations in Kerr in an ingoing radiation gauge. Our Green's functions have a frequency domain piece that…

Conserved currents for Kerr and orthogonality of quasinormal modes

Stephen R. Green, Stefan Hollands, Laura Sberna +2

We introduce a bilinear form for Weyl scalar perturbations of Kerr. The form is symmetric and conserved, and we show that, when combined with a suitable renormalization prescriptio…

New metric reconstruction scheme for gravitational self-force calculations

Vahid Toomani, Peter Zimmerman, Andrew Spiers +3

Inspirals of stellar-mass objects into massive black holes will be important sources for the space-based gravitational-wave detector LISA. Modelling these systems requires calculat…

On the radiation gauge for spin-1 perturbations in Kerr-Newman spacetime

Stefan Hollands, Vahid Toomani

We extend previous work [arXiv:1908.09095] to the case of Maxwell's equations with a source. Our work shows how to construct a retarded vector potential for the Maxwell field on th…
