Spontaneous scalarization of charged black holes in the Scalar-Vector-Tensor theory
Taishi Ikeda, Tomohiro Nakamura, Masato Minamitsuji
We present spontaneous scalarization of charged black holes (BHs) which is induced by the coupling of the scalar field to the electromagnetic field strength and the double-dual Rie…
Spontaneous scalarization of black holes in the Horndeski theory
Masato Minamitsuji, Taishi Ikeda
We investigate the possibility of spontaneous scalarization of static, spherically symmetric, and asymptotically flat black holes (BHs) in the Horndeski theory. Spontaneous scalari…
The physics of black hole binaries: geodesics, relaxation modes and energy extraction
Laura Bernard, Vitor Cardoso, Taishi Ikeda +1
Black holes are the simplest macroscopic objects, and provide unique tests of General Relativity. They have been compared to the Hydrogen atom in quantum mechanics. Here, we establ…
Gravitational Waves in Gravity: Scalar Waves and the Chameleon Mechanism
Taishi Katsuragawa, Tomohiro Nakamura, Taishi Ikeda +1
We discuss the scalar mode of gravitational waves emerging in the context of gravity by taking into account the chameleon mechanism. Assuming a toy model with a specific mat…
