Dynamical Friction as Environmental Gravitational Self-Force
Sayak Datta
Dynamical friction (DF) and gravitational-wave radiation reaction are conventionally treated as distinct dissipative mechanisms acting on a compact object inspiraling through a mat…
Tidal Stripping of Matter Bound to the Secondary in Extreme Mass-Ratio Inspirals
Sreejith Nair, Sayak Datta
Environmental studies of extreme mass-ratio inspirals (EMRIs) have focused almost entirely on matter surrounding the primary supermassive black hole. We instead consider matter bou…
Spectral suppression of black hole ringdown tails
Jose Antonio León Vega, Alejandro Svyatkovskyy Kholyavka, Sayak Datta +1
The late-time power law tail predicted by Price's law is a generic feature of black hole perturbation theory, yet it is largely absent in numerical relativity waveforms of binary b…
Shaping black hole resonances I. Black hole ringdown as a spectral filtering process
Alejandro Svyatkovskyy Kholyavka, Jose Antonio León Vega, Samuel Gómez Gómez +2
The ringdown of a perturbed black hole (BH) can be described as a superposition of quasinormal modes (QNMs), whose frequencies are determined by the spacetime geometry while their…
Axial tidal Love numbers of black holes in matter environments
Simone D'Onofrio, Sayak Datta, Andrea Maselli
We study the axial (magnetic) tidal Love numbers of a Schwarzschild black hole surrounded by a spherically symmetric matter distribution. While the formalism developed here is gene…
Geometric properties of slowly rotating black holes embedded in matter environments
Sayak Datta, Chiranjeeb Singha
Extreme mass-ratio inspirals (EMRIs) provide a precise probe of strong-field gravity, where small deviations from vacuum Kerr geometry can accumulate over many orbital cycles. In r…
