Superradiant scattering of electromagnetic waves emitted from disk around Kerr black holes
Taichi Kobayashi, Akira Tomimatsu
We study electromagnetic perturbations around a Kerr black hole surrounded by a thin disk on the equatorial plane. Our main purpose is to reveal the black hole superradiance of ele…

Disk illumination by black hole superradiance of electromagnetic perturbations
Taichi Kobayashi, Kohei Onda, Akira Tomimatsu
Using the Kerr-Schild formalism to solve the Einstein-Maxwell equations, we study energy transport due to time-dependent electromagnetic perturbations around a Kerr black hole, whi…
