Intermediate Mass Ratio Black Hole Binaries: Numerical Relativity meets Perturbation Theory

Lousto, Carlos O., Nakano, Hiroyuki, Zlochower, Yosef et al.

Understand

We study black-hole binaries in the intermediate-mass-ratio regime 0.01 < q < 0.1 with a new technique that makes use of nonlinear numerical trajectories and efficient perturbative evolutions to compute waveforms at large radii for the leading and nonleading modes.

  • As a proof-of-concept, we compute waveforms for q=1/10.
  • We discuss applications of these techniques for LIGO/VIRGO data analysis and the possibility that our technique can be extended to produce accurate waveform templates from a modest number of fully-nonlinear numerical simulations.
