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…
