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…
Analytical Fluxes from Generic Schwarzschild Geodesics
Majed Khalaf, Chris Kavanagh, Ofri Telem
We present an analytic method for computing gravitational-wave fluxes from bound Schwarzschild geodesics with arbitrary eccentricity. Our approach systematically expands the Fourie…
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…
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,…
