Abstract: K01.00057 : A Realistic Analytic Model for Complete Gravitational Wave Templates*

Their detection depends on simple, accurate, and efficient analytic templates tuned to numerical simulations of Einstein's equations of General Relativity.
Recently we developed a simple and cohesive matching method for the analytic calculation of gravitational waves by using the post-Newtonian (PN) theory for the inspiral phase and the Implicit Rotating Source (IRS) toy model for the merger phase of the binary evolution, then combined them into one complete waveform.
We extend previous work by introducing eccentricity in the inspiral model and by employing a more realistic analytic model for the merger -- the Backwards One Body (BOB) method proposed by S. McWilliams.
We test the performance of the BOB method by comparing the produced waveforms with the IRS model and the numerical results from the Simulating eXtreme Spacetimes (SXS) collaboration.
After building the inspiral and merger waveforms, we will reconstruct our matching method and validate it by comparing our results with the waveforms for the first detection, GW150914, available as open-source.
This is a rich and timely topic, and our approach is accessible and easily reproducible.
