Challenging the cosmic censorship in Einstein-Maxwell-scalar theory with numerically simulated gedankenexperiments
Fabrizio Corelli, Taishi Ikeda, Paolo Pani
We perform extensive nonlinear numerical simulations of the spherical collapse of (charged) wavepackets onto a charged black hole within Einstein-Maxwell theory and in Einstein-Max…
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…
Scalarized black holes in the presence of the coupling to Gauss-Bonnet gravity
Masato Minamitsuji, Taishi Ikeda
In this paper, we study static and spherically symmetric black hole (BH) solutions in the scalar-tensor theories with the coupling of the scalar field to the Gauss-Bonnet (GB) term…
