High-order gravitational late-time tails in Kerr spacetime
Marc Casals, Chris Kavanagh, Jakob Neef +1
The paper derives analytic high‑order late‑time decay tails of the retarded Green’s function for linear field perturbations in subextremal Kerr spacetime, giving explicit power‑law…
Post-Newtonian expansion of fluxes from a scalar charge on an inclined-spherical orbit about a Kerr black hole
Jezreel C. Castillo, Charles R. Evans, Chris Kavanagh +3
Efforts are underway to accurately model extreme-mass-ratio inspirals for binaries with a spinning (Kerr) primary. At lowest order the adiabatic evolution depends on the radiation…
Post-Newtonian expansion of gravitational energy and angular momentum fluxes: inclined spherical orbits about a Kerr black hole
Jezreel C. Castillo, Charles R. Evans, Chris Kavanagh +3
We present analytical expressions for the fluxes of energy and angular momentum from a point mass on an inclined spherical orbit about a Kerr black hole. The expressions are obtain…
Gravitational memory: new results from post-Newtonian and self-force theory
Kevin Cunningham, Chris Kavanagh, Adam Pound +3
We compute the (displacement) gravitational wave memory due to a quasicircular inspiral of two black holes using a variety of perturbative techniques. Within post-Newtonian theory,…
