Hamiltonian Formulation of Relativistic Magnetohydrodynamic Accretion on a General Spherically Symmetric and Static Black Hole: Quantum effects on Shock States

Mustapha Azreg-Aïnou, Mubasher Jamil, Sousuke Noda

In this paper, our aim is to extend our earlier work [A. K. Ahmed et al., Eur. Phys. J. C (2016) 76:280] thereby investigating an axisymmetric plasma flow with the angular momentum…

Spectroscopy of Kerr-AdS spacetime with the Heun function: Quasinormal modes, greybody factor, and evaporation

Sousuke Noda, Hayato Motohashi

We investigate quasinormal modes, greybody factor, and Hawking evaporation of a five-dimensional Kerr-anti de Sitter (AdS) black hole by solving a wave equation for a test mass…

Evaporation of Echoing Black Holes

Naritaka Oshita, Hayato Motohashi, Sousuke Noda

We compute the graybody factor and evaporation rate of a rotating black hole in the presence of a hypothetical reflective surface slightly outside the outer horizon radius, assumin…

Alfvénic superradiance for a monopole magnetosphere around a Kerr black hole

Sousuke Noda, Yasusada Nambu, Masaaki Takahashi +1

We explore superradiance for Alfvén waves (Alfvénic superradiance) in an axisymmetric rotating magnetosphere of a Kerr black hole within the force-free approximation. On the equato…

Exact solution for wave scattering from black holes: Formulation

Hayato Motohashi, Sousuke Noda

We establish an exact formulation for wave scattering of a massless field with spin and charge by a Kerr-Newman-de Sitter black hole. Our formulation is based on the exact solution…
