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 $⟨ Φ^^{2} ⟩$ 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 $⟨ Φ^^{2} ⟩_{ren}$ as well as the energy fluxes $⟨ T^_{uu} ⟩_{ren}$ and $⟨ T^_{v v} ⟩_{ren}$ (where $u$ and $v…
