Black Hole Perturbation Toolkit: Low frequency and post-Newtonian expansions
Jakob Neef, Chris Kavanagh, Adrian Ottewill
The Teukolsky and SpinWeightedSpheroidalHarmonics packages of the black hole perturbation toolkit (BHPT) are one of the main public libraries to compute numerical solutions to the…
High-order gravitational late-time tails in Kerr spacetime
Marc Casals, Chris Kavanagh, Jakob Neef +1
We calculate high-order late-time tails of the retarded Green function of the Teukolsky equation for linear field perturbations of (subextremal) Kerr spacetime. We calculate these…
Vacuum polarization and renormalized stress-energy tensor of spherical thin shells
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a thorough study of the properties of the Boulware vacuum in the spacetime of a spherical, static thin shell with a Minkowski interior. To this end, we calculate the ren…
Quantum fluxes and for a non-minimally coupled scalar field: ringdown and tail on approaching the polar Kerr inner horizon
Maria Alberti, Noa Zilberman, Marc Casals +1
We compute as well as the energy fluxes and (where and $v…
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…
