Complex frequency evolution of direct waves from binary black hole mergers
Ling Sun, Sizheng Ma, Patrick P. Chen +3
While no signal originating at a black hole's event horizon can reach future null infinity, information about the horizon and its immediate vicinity can be encoded in asymptotic pr…
Chiral symmetry and black hole isospectrality
Colin Weller, Dongjun Li, Pratik Wagle +3
We prove that black-hole isospectrality between linearly independent solutions follows whenever radiative metric and matter perturbations are reconstructed from complex master vari…
Gravitational wave signal and noise response of an optically levitated sensor in a Fabry-Pérot cavity
Andrew Laeuger, Shafaq Gulzar Elahi, Shelby Klomp +8
Optically levitated sensors inside a Fabry-Pérot cavity have been proposed for high-frequency gravitational-wave (GW) detection, though their configuration for gravitational wave…
No hair but plenty of feathers: are birds black holes?
Andrew Laeuger, Taylor Knapp
The imitative verb "chirp" is thought to originate from 16th-century Middle English. Meanwhile, this same word has been used to describe the gravitational waves (GWs) emitted from…
Prospects for High-Frequency Gravitational-Wave Detection with GEO600
Christopher M. Jungkind, Brian C. Seymour, Andrew Laeuger +1
Current ground-based interferometers are optimized for sensitivity from a few tens of Hz to about 1 kHz. While they are not currently utilized for GW detection, interferometric det…
The ringdown of a black hole surrounded by a thin shell of matter
Andrew Laeuger, Colin Weller, Dongjun Li +1
Recent studies have shown that far-field perturbations to the curvature potential of a black hole spacetime may destabilize its quasinormal mode (QNM) spectrum while only mildly af…
