Abstract

Black hole spectroscopy is the prospect of using gravitational wave emissions as a superposition of damped sinusoids, called quasinormal modes (QNMs), to determine the properties of the remnant black hole. Building on recent work by researchers in the field, we test the prospects of detectability of the QNMs of binary black hole (BBH) merger events and analyze the dependence of the first overtone on the remnant’s mass and spin. Using numerical relativity simulations from the Simulating eXtreme Spacetimes (SXS) project, we confirm for SXS:BBH:0305 that the (2,2,1) overtone features an amplitude comparable to the that of the (2,2,0) fundamental mode. We ultimately aim to develop tools that utilize LVK data to test whether the detected QNMs are consistent with our current understanding of the Kerr geometry and general relativity.
