Constraints on the Evolution of Black Hole Spin due to Magnetohydrodynamic Accretion
Masaaki Takahashi, Akira Tomimatsu
Stationary and axisymmetric ideal magnetohydrodynamic (MHD) accretion onto a black hole is studied analytically. The accreting plasma ejected from a plasma source with low velocity…

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…
