Impact of the axion-like self-interactions in gravitational atoms for LISA
Samuel Gómez Gómez, Xisco Jimenez Forteza, Carlos Palenzuela Luque
Ultralight bosons with self-interactions, such as axion-like particles, can form astrophysical Bose--Einstein condensates around stars or compact objects, often referred to as grav…
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…
Parameter Estimation with Nonstationary Noise in Gravitational-wave Data
Sumit Kumar, Alexander H. Nitz, Xisco Jiménez Forteza
The sensitivity of gravitational-wave (GW) detectors is characterized by their noise curves, which determine the detector's reach and ability to measure the parameters of astrophys…
