Gravitational wave lensing as a probe of halo properties and dark matter
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Just like light, gravitational waves (GWs) are deflected and magnified by gravitational fields as they propagate through the Universe. However, their low frequency, phase coherence…
Lensing of gravitational waves: efficient wave-optics methods and validation with symmetric lenses
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Gravitational wave (GW) astronomy offers the potential to probe the wave-optics regime of gravitational lensing. Wave optics (WO) effects are relevant at low frequencies, when the…
Nonlinear effects in black hole ringdown
Mark Ho-Yeuk Cheung, Vishal Baibhav, Emanuele Berti +8
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescen…
Stability of the fundamental quasinormal mode in time-domain observations against small perturbations
Emanuele Berti, Vitor Cardoso, Mark Ho-Yeuk Cheung +4
Black hole spectroscopy with gravitational waves is an important tool to measure the mass and spin of astrophysical black holes and to test their Kerr nature. Next-generation groun…
