Gravitational-wave memory from coalescing binaries

POSTER

Abstract

The nonlinear or Christodoulou memory is a non-oscillatory contribution to the gravitational-wave signal that arises from the gravitational-wave stress energy tensor. Using a semi-analytic approach we generate memory signals for a range of binary black hole parameters, extending previous work. We also---for the first time---compute the nonlinear memory for binary neutron star mergers. These waveforms will be useful for future searches of the nonlinear memory in ground and space-based detectors.
