Binary black hole merger gravitational waves and recoil in the large mass ratio limit

Sundararajan, Pranesh A., Khanna, Gaurav, Hughes, Scott A.

Understand

Spectacular breakthroughs in numerical relativity now make it possible to compute spacetime dynamics in almost complete generality, allowing us to model the coalescence and merger of binary black holes with essentially no approximations.

  • The primary limitation of these calculations is now computational.
  • In particular, it is difficult to model systems with large mass ratio and large spins, since one must accurately resolve the multiple lengthscales which play a role in such systems.
  • Perturbation theory can play an important role in extending the reach of computational modeling for binary systems.
