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…
Blandford-Znajek process as Alfvénic superradiance
Sousuke Noda, Yasusada Nambu, Takuma Tsukamoto +1
The superradiant scattering of Alfvén waves (Alfvénic superradiance) in a forcefree magnetosphere is discussed to reveal the relationship between the Blandford-Znajek (BZ) process…
Sequestering Mechanism in Scalar-Tensor Gravity
Takuma Tsukamoto, Taishi Katsuragawa, Shin'ichi Nojiri
We make a theoretical prediction for the ratio of the dark energy to other components in the Universe based on the scenario of the sequestering mechanism which was recently propose…
