Frequency and decay time (half-life) of the different ringdown tones measured in GW250114.

Caption

Left panel: Frequency and decay time (half-life) of the different ringdown tones measured in GW250114. The black markers indicate the values predicted for a Kerr black hole. Right panel: gravitational-wave signal (bottom spiral) emitted by the remnant black hole (bottom sphere) into the different tones, for a numerical simulation matching the measured parameters of GW250114.
