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…
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…
Binary black holes in the heat of merger
Samanwaya Mukherjee, Sayak Datta, Sukanta Bose +1
A black hole binary approaching merger undergoes changes in its inspiral rate as energy and angular momentum are lost from the orbits into the horizons. This effect strengthens as…
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…
