 Hawking radiation by spherically-symmetric static black holes for all spins: I -- Teukolsky equations and potentials / Arbey, Alexandre ; Auffinger, Jérémy ; Geiller, Marc ; Livine, Etera R. ; Sartini, Francesco In the context of the dynamics and stability of black holes in modified theories of gravity, we derive the Teukolsky equations for massless fields of all spins in general spherically-symmetric and static metrics.
