• Black hole spectroscopy in the next decade 

      Cabero, Miriam; Westerweck, Julian; Capano, Collin D.; Kumar, Sumit; Nielsen, Alex Bentley; Krishnan, Badri (Peer reviewed; Journal article, 2020)
      Gravitational wave observations of the ringdown of the remnant black hole in a binary black hole coalescence provide a unique opportunity of confronting the black hole no-hair theorem in general relativity with observational ...
    • 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 ...
