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…

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

Computation of $⟨ I^¦^{2} ⟩$ and quantum fluxes at the polar interior of a spinning black hole

Noa Zilberman, Marc Casals, Adam Levi +2

Renormalization of physical quantities for quantum field theories in curved spacetimes can be achieved via the consistent subtraction of counterterms within a regularization scheme…
