Multimode Quasinormal Spectrum from a Perturbed Black Hole
Capano, Collin D.; Cabero, Miriam; Westerweck, Julian; Abedi, Jahed; Kastha, Shilpa; Nitz, Alexander H.; Wang, Yi-Fan; Nielsen, Alex Bentley; Krishnan, Badri (Peer reviewed; Journal article, 2023)When two black holes merge, the late stage of gravitational wave emission is a superposition of exponentially damped sinusoids. According to the black hole no-hair theorem, this ringdown spectrum depends only on the mass ... -
Spectroscopy for asymmetric binary black hole mergers
Abedi, Jahed; Capano, Collin D.; Kastha, Shilpa; Nitz, Alexander H.; Wang, Yi-Fan; Westerweck, Julian; Nielsen, Alex Bentley; Krishnan, Badri (Peer reviewed; Journal article, 2023)Black hole spectroscopy is the proposal to observe multiple quasinormal modes in the ringdown of a binary black hole merger. In addition to the fundamental quadrupolar mode, overtones and higher harmonics may be present ...
