Non-linear black hole ringdowns: An analytical approach

Due to the nature of gravity, non-linear effects are left imprinted in the quasi-normal modes generated in the ringdown phase of the merger of two black holes. We offer an analytical treatment of the quasi-normal modes at second-order in black hole perturbation theory which takes advantage from the fact that the non-linear sources are peaked around the light ring. As a byproduct, we describe why the amplitude of the second-order mode relative to the square of the first-order amplitude depends only weakly on the initial condition of the problem.

  • Effect: nonlinear
  • Black hole: quasinormal mode
  • Gravitation
  • Perturbation theory: higher-order
  • Boundary condition
  • Black hole: binary: coalescence
  • Higher-order: 2
  • Black hole: perturbation
