Abstract: We prove boundedness and polynomial decay statements for solutions to the spin $\pm1$ Teukolsky-type equation projected to the $\ell=1$ spherical harmonic on Reissner-Nordstr{\"o}m spacetime. The equation is verified by a gauge-invariant quantity which we identify… read more here.

DOI: 10.1088/1361-6382/ac28e3
Abstract: We show that generic linear perturbations ψ solving □gψ+αl2ψ=0 on Reissner–Nordström–AdS black holes have infinite local energy at the Cauchy horizon. Combined with the result of Kehle (2020 Commun. Math. Phys. 376 145–200) that such… read more here.
