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…
