Dynamical Tidal Response of Non-rotating Black Holes: Connecting the MST Formalism and Worldline EFT
Hajime Kobayashi, Shinji Mukohyama, Naritaka Oshita +2
The response of a black hole (BH) to tidal forces encodes key information about the underlying gravitational theory and affects the waveform of gravitational waves emitted during b…
Exorcising ghosts with gravitational waves: cases of ghostful and ghost-free fourth-order gravity
Gaetano Lambiase, Shinji Mukohyama, Tanmay Kumar Poddar +1
General Relativity (GR) is an effective field theory valid in the infrared regime. Quadratic curvature extensions intended to probe ultraviolet physics generically propagate a mass…
Effective Field Theory of Perturbations on Arbitrary Black Hole Backgrounds with Spacelike Scalar Profile
Shinji Mukohyama, Emeric Seraille, Kazufumi Takahashi +1
We develop the effective field theory (EFT) of perturbations in the context of scalar-tensor theories with a spacelike scalar profile on arbitrary black hole backgrounds. Our const…
Constraining Cubic Curvature Corrections to General Relativity with Quasi-Periodic Oscillations
Alireza Allahyari, Liang Ma, Shinji Mukohyama +1
We investigate observational constraints on cubic curvature corrections to general relativity by analyzing quasi-periodic oscillations (QPOs) in accreting black hole systems. In pa…
Parametrized Tidal Dissipation Numbers of Non-rotating Black Holes
Hajime Kobayashi, Shinji Mukohyama, Naritaka Oshita +2
A set of tidal dissipation numbers (TDNs) quantifies the absorption of the tidal force exerted by a companion during an inspiralling phase of a binary compact object. This tidal di…
Quasinormal Modes from EFT of Black Hole Perturbations in Vector-Tensor Gravity
Shogo Tomizuka, Hajime Kobayashi, Naritaka Oshita +2
We study the dynamics of odd-parity perturbations on a static and spherically symmetric black hole background with a timelike vector field based on the effective field theory (EFT)…
