Dynamical tidal Love numbers of black holes under generic perturbations: Connecting black hole perturbation theory with effective field theory
Sumanta Chakraborty, M. V. S Saketh, Tanja Hinderer +1
The foundation for modeling the coupling of the internal structure of compact objects in binary systems to their dynamics and emitted gravitational waves is a systematic effective…
Strong-field Gravitational Wave Lensing in the Kerr Background
M. V. S. Saketh, Rajes Ghosh, Anuj Mishra
Gravitational-wave (GW) lensing can encode valuable information about the properties of the intervening lens, but most existing studies remain restricted to the small-deflection, w…
Kerr-Newman quasinormal modes and Seiberg-Witten theory
Hector O. Silva, Jung-Wook Kim, M. V. S. Saketh
It was recently suggested the quasinormal-mode spectrum of black holes is related to a class of four-dimensional super Yang-Mills theories described by Seiberg-Witt…
Investigating tidal heating in neutron stars via gravitational Raman scattering
M. V. S. Saketh, Zihan Zhou, Suprovo Ghosh +2
We present a scattering amplitude formalism to study the tidal heating effects of nonspinning neutron stars incorporating both worldline effective field theory and relativistic ste…
Modeling horizon absorption in spinning binary black holes using effective worldline theory
M. V. S. Saketh, Jan Steinhoff, Justin Vines +1
The mass and spin of black holes (BHs) in binary systems may change due to the infall of gravitational-wave (GW) energy down the horizons. For spinning BHs, this effect enters at 2…
Scattering of gravitational waves off spinning compact objects with an effective worldline theory
M. V. S. Saketh, Justin Vines
We study the process, within classical general relativity, in which an incident gravitational plane wave, of weak amplitude and long wavelength, scatters off a massive spinning com…
Conservative and radiative dynamics in classical relativistic scattering and bound systems
M. V. S. Saketh, Justin Vines, Jan Steinhoff +1
As recent work continues to demonstrate, the study of relativistic scattering processes leads to valuable insights and computational tools applicable to the relativistic bound-orbi…
